"If it was easy, everybody would be doing it. It isn't, and they don't."
—Me -
"Life is not a matter of holding good cards, but of playing a poor hand well."
–Josh Billings (pseudonym of Henry Wheeler Shaw), Josh Billings on Ice, and Other Things (1868) (erroneously attributed to Robert Louis Stevenson, among others) -
“I am still learning.”
—Domenico Giuntalodi (but misattributed to Michelangelo Buonarroti (common phrase throughout 1500's)). -
"Love work; hate mastery over others; and avoid intimacy with the government."
—Shemaya, in the Thalmud -
"It is a pleasant world we live in, sir, a very pleasant world. There are bad people in it, Mr. Richard, but if there were no bad people, there would be no good lawyers."
—Charles Dickens, “The Old Curiosity Shop ... With a Frontispiece. From a Painting by Geo. Cattermole, Etc.” 255 (1848) -
"A system of law that not only makes certain conduct criminal, but also lays down rules for the conduct of the authorities, often becomes complex in its application to individual cases, and will from time to time produce imperfect results, especially if one's attention is confined to the particular case at bar. Some criminals do go free because of the necessity of keeping government and its servants in their place. That is one of the costs of having and enforcing a Bill of Rights. This country is built on the assumption that the cost is worth paying, and that in the long run we are all both freer and safer if the Constitution is strictly enforced."
—Williams v. Nix, 700 F. 2d 1164, 1173 (8th Cir. 1983) (Richard Sheppard Arnold, J.), rev'd Nix v. Williams, 467 US. 431 (1984). -
"The criminal goes free, if he must, but it is the law that sets him free. Nothing can destroy a government more quickly than its failure to observe its own laws, or worse, its disregard of the charter of its own existence."
—Mapp v. Ohio, 367 U.S. 643, 659 (1961). -
"Any costs the exclusionary rule are costs imposed directly by the Fourth Amendment."
—Yale Kamisar, 86 Mich.L.Rev. 1, 36 n. 151 (1987). -
"There have been powerful hydraulic pressures throughout our history that bear heavily on the Court to water down constitutional guarantees and give the police the upper hand. That hydraulic pressure has probably never been greater than it is today."
— Terry v. Ohio, 392 U.S. 1, 39 (1968) (Douglas, J., dissenting). -
"The great end, for which men entered into society, was to secure their property."
—Entick v. Carrington, 19 How.St.Tr. 1029, 1066, 95 Eng. Rep. 807 (C.P. 1765) -
"It is a fair summary of history to say that the safeguards of liberty have frequently been forged in controversies involving not very nice people. And so, while we are concerned here with a shabby defrauder, we must deal with his case in the context of what are really the great themes expressed by the Fourth Amendment."
—United States v. Rabinowitz, 339 U.S. 56, 69 (1950) (Frankfurter, J., dissenting) -
"The course of true law pertaining to searches and seizures, as enunciated here, has not–to put it mildly–run smooth."
—Chapman v. United States, 365 U.S. 610, 618 (1961) (Frankfurter, J., concurring). -
"A search is a search, even if it happens to disclose nothing but the bottom of a turntable."
—Arizona v. Hicks, 480 U.S. 321, 325 (1987) -
"For the Fourth Amendment protects people, not places. What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection. ... But what he seeks to preserve as private, even in an area accessible to the public, may be constitutionally protected."
—Katz v. United States, 389 U.S. 347, 351 (1967) -
“Experience should teach us to be most on guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded
rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.”
—United States v. Olmstead, 277 U.S. 438, 479 (1925) (Brandeis, J., dissenting)
-
“Liberty—the freedom from unwarranted intrusion by government—is as easily lost through insistent nibbles by government officials who seek to do their jobs too well as by those whose purpose it is to oppress; the piranha can be as deadly as the shark.”
—United States v. $124,570, 873 F.2d 1240, 1246 (9th Cir. 1989) -
"You can't always get what you want / But if you try sometimes / You just might find / You get what you need."
—Mick Jagger & Keith Richards, Let it Bleed (album, 1969) -
"In Germany, they first came for the communists,
and I didn't speak up because I wasn't a communist. Then they came for the Jews,
and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists,
and I didn't speak up because I wasn't a trade unionist. Then they came for
the Catholics and I didn't speak up because I wasn't a Catholic. Then they came
for me–and by that time there was nobody left to speak up."
—Martin Niemöller (1945) [he served seven years in a concentration camp] -
“Children grow up thinking the adult world is ordered, rational, fit for purpose. It’s crap. Becoming a man is realising that it’s all rotten. Realising how to celebrate that rottenness, that’s freedom.”
– John le Carré, The Night Manager (1993), line by Richard Roper -
"The point of the Fourth Amendment, which often is not grasped by zealous officers, is not that it denies law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime."
—Johnson v. United States, 333 U.S. 10, 13-14 (1948) -

Following Devenpeck v. Alford, 543 U.S. 146, 153 (2004), “an officer’s ‘subjective reason for making the arrest need not be the criminal offense as to which the known facts provide probable cause.’” Brincken v. Voss, 2016 U.S. App. LEXIS 21101 … Continue reading

MS: Delay for dog sniff doesn’t seem to matter in Mississippi if the dog is already there
The court holds essentially that it didn’t matter whether there was reasonable suspicion or not for a dog sniff after a traffic stop. Also, there’s no ineffective assistance claim to a forfeiture. In re One Hundred Thirtyseven Thousand Three Hundred … Continue reading
CA7: RS of drugs in a backpack was justification for frisk for gun; taking key to do a protective sweep of apt before seeking consent was valid on this record
Defendant’s frisk for weapons was justified because there was reasonable suspicion he had drugs in a backpack that had been deposited in an apartment, which defendant lied about going to. Drugs and firearms “go hand in hand,” (See, e.g., United … Continue reading
N.D.Cal.: Officers knew or should have known target location was multifamily; SW for gun in one unit didn’t permit search of all five
“The issue in defendant Josue Olman Martinez’s motion to suppress is whether it was reasonable for officers to continue to search a property that they may have initially assumed was a single family residence once they knew or should have … Continue reading
E.D.N.C.: CSLI warrant didn’t show PC on informant information or timeliness; GFE did not apply
The prospective CSLI warrant failed to show probable cause on the facts of informant hearsay or overcome staleness, and the motion to suppress is granted. (Also, the owner of a cell phone has standing to challenge GPS tracking of his … Continue reading
SD: Exigent circumstances justified warrantless entry into def’s apartment in case there was an injured victim inside
Exigent circumstances supported the warrantless entry into defendant’s apartment. A witness told the police he’d been asked to move a body and he did move a heavy suitcase, big enough to hold the body of a woman. He didn’t know … Continue reading
E.D.N.C.: No PC for GPS information from any phone that connected to the target phone; and no GFE
“Because the first pen order allowed officers to retrieve GPS location information about any phone which contacted the target phones, and nothing in the affidavit shows the relation between those contacting phones and the underlying criminal activity, the magistrate judge … Continue reading
AZ: No state const’l right to RS for a parole search; good policy reasons for suspicionless parole searches
In a wide ranging opinion on parole searches, the Arizona court holds that there is no Fourth Amendment or state constitutional requirement of reasonable suspicion for a parole search. There are good policy reasons for suspicionless searches. State v. Adair, … Continue reading
IA: Dog alert on car and search of car that produces nothing permits search of the person who was sitting where the dog alerted
After seeing a woman with a backpack run to a car with the engine running in an empty parking lot of a closed business, the officer decided to inquire. They had inconsistent stories about where they’d been and what they … Continue reading
UT: Roommates had apparent authority to consent to search of a room they seldom entered, but they could, and that’s the point
The state had two justifications for the entry. First, the other occupants had the ability to consent to entry into the room even though they didn’t regularly go there. Second, blood on the floor showed exigency. Met v. State, 2016 … Continue reading
S.D.Fla.: Collective knowledge requires that the stopping officers have some knowledge of the reason for the stop
Collective knowledge doesn’t apply where the officers making the stop were not informed of what the DEA didn’t communicate. The stop was, however, valid based on traffic violations. The drug dog showed up while the main part of the traffic … Continue reading
E.D. Tenn.: “Premises” in the broad consent to search form is interpreted to include vehicles parked outside
The use of “premises” in the broad consent to search form is interpreted to include vehicles parked outside near the house. United States v. Foster, 2016 U.S. Dist. LEXIS 161550 (E.D. Tenn. Nov. 22, 2016). “The record contains no evidence … Continue reading
IA: Ordering def off his porch and out to the driveway is a seizure
“[W]e conclude that White was seized within the meaning of the Fourth Amendment when Officer Stricker directed White to step off of the front porch and onto the driveway. We reach this conclusion for several reasons. …” State v. White, … Continue reading
OH3: Showing of PC justified nexus to SW for def’s home
There was probable cause to believe that evidence of defendant’s gambling and money laundering would be found in his home because he could store records at home and run his business from there. State v. Robinson, 2016-Ohio-7823, 2016 Ohio App. … Continue reading
OH3: Burning MJ on lot next to def, with his admission to firefighters it was his MJ and fire, justified knock-and-talk
The fire department was called to an open burn, and the police came along, too. There was the apparent smell of burning marijuana. The officers went to the nearest structure next door for a knock-and-talk about the burning marijuana. The … Continue reading
