"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.

KY: Real time pinging of CSLI requires SW except for exigency
“[W]e hold that individuals have a reasonable expectation of privacy in real-time CSLI and, consequently, the acquisition of such data by the police constitutes a search triggering the protections of the Fourth Amendment. Furthermore, the good faith exception does not … Continue reading
PA: Realtime CSLI also subject to Carpenter; orders here under state wiretap act complied with 4A
The state obtained realtime CSLI with court orders under the state wiretapping statute, and these orders were sufficiently like search warrants under Dalia v. United States. (Carpenter was decided while his case was on appeal.) The court finds that the … Continue reading
D.R.I.: Carpenter procedural and not substantive and not a “new rule” under Teague
Carpenter is not entitled to retroactive application to post-conviction cases under Teague. It is procedural, not substantive. United States v. Sandoval, 2020 U.S. Dist. LEXIS 11281 (D.R.I. Jan. 23, 2020):
NJ: State failed to show exigency for warrantless phone records search

CSLI obtained by court order, but without showing probable cause, nearly three years before Carpenter was all in good faith. Watson v. State, 2020 Ala. Crim. App. LEXIS 4 (Jan. 10, 2020). Defendant’s ineffective assistance of counsel claim against counsel … Continue reading

NY2: Responding to a domestic call, the unmistakable sounds of an assault from inside justified warrantless entry

CA4: Police could warrantlessly seize CSLI for cell phone abandoned in flight from the police
Defendant consciously was abandoning his property as he was trying to elude police who were chasing him on foot. He tossed everything, including his cell phone. Getting the CSLI for the abandoned phone without a warrant was reasonable, too. United … Continue reading
N.D.Ind.: Parole search waiver applies to CSLI information
CSLI can be obtained from a parolee’s cell phone without a search warrant. “However, the Court’s own research has found that every circuit court faced with the same question has sided with the Government and found that a warrant is … Continue reading
FL4: Use of cell site simulator under CSLI order 4A violation; no GFE because of lack of contrary authority
In 2012, well before Carpenter, the police used a cell site simulator under CSLI order to track defendant. There was no binding authority at the time for the state to rely on. By the time this case reaches appeal, the … Continue reading
E.D.Wis.: Cert grant alone in Carpenter didn’t nullify GFE as to CSLI
The fact that SCOTUS had granted cert in Carpenter when the CSLI was obtained under a § 2703 order and not a search warrant doesn’t make government reliance on existing precedent unreasonable or show a lack good faith. United States … Continue reading

VA: State gets to argue GFE after a Carpenter remand even though it never raised the question before Carpenter was decided
Defendant was the subject of warrantless CSLI pre-Carpenter, and he petitioned for cert while Carpenter was pending. After Carpenter was decided, his case was GVR’d back to the state court of appeals. Reed v. Virginia, 138 S. Ct. 2702 (2018). … Continue reading
CA5: CSLI obtained prior to Carpenter was valid, and it didn’t taint CSLI obtained after Carpenter for backup
Defendant was suspected of being a serial bank robber in the Houston area, and the government obtain CSLI by an SCA § 2703(d) order without a showing of probable cause. Two months before trial, Carpenter was decided, and, that same … Continue reading

WA: Cell phone ping was a search, but here it was reasonable because of exigency
A cell phone ping is a search under the Fourth Amendment and Washington Constitutions requiring a warrant. It was reasonable here, however, because of exigent circumstances because defendant was a suspect, and the police feared he’d fled. State v. Muhammad, … Continue reading
