After reviewing GA and TN gun laws, there seems no difference. A defense to a violation is the permit. A cop in GA sees your OCed handgun and cannot (yeah right
) stop you to see if you are permitted. The same in TN except there is not language preventing a TN cop from jacking you up to check your papers. Either way, the cop bears the burden of being a rights violating goon or not.
Secondly, a kid walking the neighborhood knocking on doors is not the point, the point is he suspicious and worthy of detaining because a cop "does not like the cut of his jib"...or that "he [the kid going door to door] don't like right" to the cop.
US v. Black and Terry v. Ohio are one in the same except in Black the court got it right by telling the cops they got it wrong. Thereby tossing the gun evidence cuz cops did not have even RAS to detain Black. So, the 4th Circuit, in my view, ignored Terry where Black was concerned.
Which brings me back to the op, no-knocks are against the law cuz cops must use past data to presume that a person of interest is in the target house unless they observe directly that the target in the residence. Another "hunch"..."Well, we sawr the bad guy was there one time last week so he must be there now!"...BREACH!!!!!
