Whether or not they care may still an issue, unfortunately.
I've sent them footage, along with the name of the guy who's face it was and they did fuck all. The guy's in jail now though a few years later for beating his wife.
I had video of someone opening my mailbox, rifling through the mail, and stealing a check. Neither the NYPD nor the USPS gave a damn, despite this being a federal crime.
My neighbor did the same thing (not on good terms; allegedly looking for misdelivered mail) and again, no penalty despite having clear video of the crime. At least if he does anything else I can it out then and show his previous malfeasance.
The elective public officials seems to response to these emails very fast and the head of police is CC.
The public official will put your email to their own email list - I don't mind that and support them if they act to provide solution to the community problems.
