Carrying is NOT “probable cause”!
Anybody at any time “could be a felon”, or in the country illegally....
Amen!
By way of analogy —
“I pulled 26 year-old Mr and Mrs. Demtricus and La Shonda Greene over because they were observably black (African-American) in a Mercedes S500 in a nice neighborhood, and I needed to ascertain they had not stolen the car or were otherwise engaged, or intended to engage in felonious actions. They were initially indignant and refused to provide ID, so I arrested them for DTP and had their car impounded. I was unaware Mr. Greene had recently signed with the Green Bay Packers.”
The specifics differ, but the principle(s) is the same.
Not everyone gets a call to be investigated. What should the police have done? They couldn’t just walk in, look and walk out could they? They asked for ID, which I feel is OK and should be complied with. After that, it went wrong.
