Nice sentiment, but I don’t give cops a pass for emotional considerations.
Just from experience, and knowing a few details... I think it’s likely the teens and/or mom did something stupid, and appeared aggressive to the cops. Given the dangers inherent to the area they were in, I think it’s reasonable to be less tolerant of aggressive behavior than under "normal" circumstances.
Cops also have the right to self protection. If they were honestly trying to secure their own safety, and had reasonable cause to act upon a belief that they were in danger … Constitutional principles were upheld, not trampled upon.
Whether the teens actually posed a danger, and what they were doing is irrelevant. What matters is … what the police reasonably believed the teens were doing.
not enough info to judge, imo.
Keep smiling ... it'll just make 'em wonder what you're up to...
