Potential defenses to a case plaintiff was arrested for do not nullify the probable cause. Chiaverini v. City of Napoleon, 2023 U.S. App. LEXIS 865 (6th Cir. Jan. 11, 2023):
Simply put, Chiaverini’s potential defenses to a crime don’t affect the initial probable cause determination. Ideally, perhaps, officers investigating allegations like these might inquire into obvious explanations or defenses that a prosecutor can consider. But nothing required the police to investigate Chiaverini’s affirmative defense. Fridley, 291 F.3d at 873 (“[I]t is not a routine part of the prearrest investigation for police officers to inquire into affirmative defenses.”) Although “innocent explanations . . . may exist,” they don’t “render the  determination of probable cause invalid.” United States v. Martin, 289 F.3d 392, 400 (6th Cir. 2002); see United States v. Terry, 522 F.3d 645, 648-49 (6th Cir. 2008) (explaining that probable cause “does not require ‘near certainty,’ only a ‘fair probability'” (citation omitted)). And we have explained that “the Fourth Amendment does not require that a police officer know a crime has occurred at the time the officer arrests or searches a suspect.” United States v. Strickland, 144 F.3d 412, 415 (6th Cir. 1998).

"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."

bear heavily on the Court to water down constitutional guarantees and give the

"It is a fair summary of history to say that the safeguards of liberty have

"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."
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.”

“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.”

"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
