"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) -
The book was dedicated in the first (1982) and sixth (2025) editions to Justin William Hall (1975-2025). He was three when this project started in 1978.

CA6: Realtime cell phone GPS tracking of a fugitive for 7+ hours was not a “search”
Realtime cell phone GPS tracking of a fugitive for 7+ hours was not a “search” under the Fourth Amendment, following United States v. Skinner, 690 F.3d 772, 781 (6th Cir. 2012). United States v. Riley, 2017 U.S. App. LEXIS 9900 … Continue reading
SCOTUS: cert granted in CSLI case; third-party doctrine to be revisited, but how will it turn out?

E.D.Va.: There is no higher nexus requirement involving cell phone data and tracking
There is no higher nexus requirement involving cell phones. A ping order of a cell phone may be used to collect “mere evidence,” rejecting United States v. Powell, 943 F. Supp. 2d 759 (E.D. Mich. 2013). United States v. Christian, … Continue reading

CA5: Prospective CSLI is a records request, and it is not subject to the Fourth Amendment
A court order for prospective cell site location information is a records request, and it is not subject to the Fourth Amendment. United States v. Wallace, 2017 U.S. App. LEXIS 8914 (5th Cir. May 22, 2017), substituted opinion 2017 U.S. … Continue reading
OH5: Def without DL and not on rental agreement as authorized driver had no standing
Defendant never had a DL, and he was driving a rental car and wasn’t on the paperwork as an authorized driver, so the renter had no authority to let him drive. Therefore, he lacked standing. State v. Nicholson, 2017-Ohio-2825, 2017 … Continue reading
BNA: Can You Hear Them Now? Robbers Ask SCOTUS for Phone Privacy
BNA: Can You Hear Them Now? Robbers Ask SCOTUS for Phone Privacy by Jordan S. Rubin: From Criminal Law Reporter
IN: CSLI is third-party information for which SW not required [noting pending cert. petitions]
The third party doctrine is still alive and well, and the collection of CSLI does not implicate Fourth Amendment concerns. Zanders v. State, 2017 Ind. LEXIS 339 (May 4, 2017):
WaPo: Will the Supreme Court agree to hear the Fourth Amendment cell-site cases? (And should they?)
WaPo: Will the Supreme Court agree to hear the Fourth Amendment cell-site cases? (And should they?) by Orin Kerr: As John Elwood noted recently at SCOTUSblog, the Supreme Court has relisted a set of pending cert petitions on whether the … Continue reading
TX: Texas Const. grants no special protection to third party information; here CSLI and numbers dialed
Third party cell phone information is not protected by the Texas Constitution. It grants no greater rights than the Fourth Amendment. If the drafters wanted it broader, they could have said so. The information was available to law enforcement under … Continue reading
S.D.Ind.: T-Mobile’s policy to do a data dump on any T-Mobile phone linked to a robbery of one of its stores doesn’t make it a government agent
A T-Mobile store was robbed, and their policy is to do a data dump including CSLI of any T-Mobile phone number potentially linked to the robbery. That does not make them a government agent in the data dump. United States … Continue reading

S.D.N.Y.: Sporadic user of cell phone had no standing; gathering provider information not a “search”
Defendant moved to suppress the cell phone data from a phone he sporadically used during a conspiracy, but he has no standing. The date was 334 days worth, and his use was occasional. This is no different that a sporadic … Continue reading
CA6: CSLI by court order was valid; lengthy pole camera observation of publicly seen areas reasonable
Lengthy CSLI was obtained by a cell site simulator but with a court order. Pleading the pen register statute is no help to the defense because there is no exclusionary remedy. Pre-Jones GPS tracking was valid under Davis. Finally, lengthy … Continue reading

BuzzFeed: Gorsuch Might Play Key Role In Cellphone Privacy Issues If Confirmed To The Supreme Court by Hamza Shaban: The Court is likely to consider cellphone location data, encryption, and other privacy issues in the coming years.
N.D.Ill.: While merely being close to another for whom there is reason to frisk or arrest is not PC, here there actually was PC
The FBI had more than reasonable suspicion based on mere propinquity to others. There were specific facts involving defendant that rose to reasonable suspicion. United States v. Amaya, 2016 U.S. Dist. LEXIS 174615 (N.D.Ill. Dec. 16, 2016).* Defendant’s cell site … 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
E.D.Pa.: CSLI warrant upheld
CSLI warrant upheld: “ The cell site data obtained by the government is admissible because the government’s actions did not constitute a ‘search’ falling under the protection of the Fourth Amendment. Even if the government had violated the Fourth Amendment, … Continue reading
