Texas cops say they followed policy by arresting and handcuffing, processing, photographing, and fingerprinting 11-year-old girl over alleged false fire alarm at school
People could also die choking on food. Do you want 11 year olds arrested for cooking?
Seriously though, the severity of the ACTUAL reaction should never be based on unlikely hypotheticals.
FD might not be able to respond to an actual fire.
Another hypothetical. Also something that could happen for other reasons, such as for example road work. Do you want people arrested for doing their job at inopportune moments too?
So far the kid hasn't been charged with anything
Making it an unnecessary and overzealous arrest
being arrested is probably a good motivation to not do that again.
Or to (rightfully) despise and fear cops for the rest of her life. If she's ever in trouble or sees someone else in trouble, do you think her first instinct is to reach out to her abusers for help?
TL;DR: NO it wasn't justified and NO, nothing good will come from it.
Quite the opposite: Lawful Evil cops being evil by following, enforcing and demanding unjust rules.
Chaotic Good is more like people doing as much good as they can by trying to change the rules into just ones or simply doing something right that's against the rules.
