A domestic violence call doesn’t per se mean there is reasonable suspicion. The circumstances of the call have to be evaluated on arrival at the scene from all the circumstances. Thomas v. Dillard, 2016 U.S. App. LEXIS 8679 (9th Cir. May 5, 2016):
As a general category of crime, therefore, domestic violence is clearly distinguishable from the more specific crimes the Supreme Court and this court have held are likely to involve the use of weapons, such as the daytime store robbery in Terry, bank robbery or narcotics trafficking. Although mail theft and bank robbery both fall under the category of theft offenses, only the latter gives rise to suspicion a suspect is armed. Compare Flatter, 456 F.3d at 1158, with Johnson, 581 F.3d at 1000. Likewise, illicit drug use, large-scale marijuana cultivation and narcotics trafficking are all drug offenses, but only the latter two give rise to reasonable suspicion for a Terry frisk. Compare Ramirez, 560 F.3d at 1022, with Davis, 530 F.3d at 1082-83, and $109,179 in U.S. Currency, 228 F.3d at 1086-87. As with the general categories of theft and drug offenses, domestic violence encompasses too broad an array of crimes to categorically justify reasonable suspicion under Terry and its progeny.
Given the breadth of domestic violence, the specific circumstances of a call must be factored into the reasonable suspicion analysis. Some domestic violence calls may pose serious threats to officers, such as those requiring an officer to enter a suspect’s home and intervene in the middle of a heated fight or vicious attack. See Mattos, 661 F.3d at 457 (Kozinski, C.J., concurring in part and dissenting in part) (noting that by entering the home, officers may “become targets of fear and anger” and are “in close quarters, ‘at the disadvantage of being on [their] adversary’s turf'” (quoting Buie, 494 U.S. at 333)). Other examples are those involving a suspect angrily threatening a responding officer to get off his property, see Reed v. Hoy, 909 F.2d 324, 325 (9th Cir. 1989), overruled on other grounds by Edgerly v. City & Cty. of San Francisco, 599 F.3d 946, 956 n.14 (9th Cir. 2010), or a report of a suspect wielding a gun, see George v. Morris, 736 F.3d 829, 832 (9th Cir. 2013). But not all domestic violence calls present such risks. Reasonable suspicion must be based on “specific and articulable facts” regarding the suspect and the “particular circumstances,” rather than “unparticularized suspicion.” Terry, 392 U.S. at 21, 27. “This demand for specificity in the information upon which police action is predicated is the central teaching of [the Supreme] Court’s Fourth Amendment jurisprudence.” Id. at 21 n.18. We reject the notion there is a blanket “domestic violence” exception to Terry’s requirement for particularized suspicion.

"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."

"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)
