So, out of the 1000’s of “people of interest” that are ID’d every week or so, you mention two bad examples and generalize for everyone. Look at the PA State Trooper killing last week. Couple persons of interest quickly ID’d and exonerated. Now they are looking for the real killer.
My point, that if announced to the public that you are a Person of Interest, it makes sense to lawyer up. .
There is no such thing whatsoever as a “person of interest” legally. If they call you that, you are a suspect.
