It pretty much is Unreasonable, and should be considered so, in general.
Profiling is a distasteful tool which is ripe for abuse and should only be considered rarely, in extreme circumstances, say, maybe, for example, if one specific ideological group professes and/or acts on beliefs which are, say, antithetical to American Freedom, and advocate, say, turning the USA into an Islamic Caliphate via Acts of War.
You know, some Extreme Threat like that. War. Not simply for routine or arbitrary reasons to stop and frisk average Citizens.
What if a person matching the description of a known criminal is seen leaving a building known to have “problems”? They haven’t done anything. Should they be stopped and questioned? What if police with the permission of the building owner make a patrol of a building and stop, question, and frisk certain people?
I want a strong check on police. On the other hand, some areas require a strong hand. A lot of this stemmed from claims of “racial profiling”. I don’t know if these claims are truly justified or just whining. Large cities are tough places to live. I don’t like em. I left. I got sick of women being attacked on the sidewalk and the perp gone before I could get down there. Or having my car broke into while in a friend’s apartment for five minutes when picking them up. et cetera.
Yes I am not referring to arbitrary stop and frisk, or even random checkpoints. I am referring to specific profiling for specific crimes.
