Documenting Police Tech in Our Communities with Open Source Research

@eff ANPR is used a ton here if I'm not wrong, I've seen TV shows where they can track a vehicles direction (which contains a 'fugitive') in real time
@eff Local news out here just had a feel good story about how they’re great for solving crimes.
@rosanita @eff so might stationing a police officer in each home, but I wouldn't applaud for that either. Personally I regard this technology as pure overreach by law enforcement, casting out dragnets for thoughtcrimes with no probable cause whatsoever.
@eff Colorado State Parks pass available at significant discount w/car registration (IIRC $29 vs. $80 retail) but no windshield sticker for proof. (Registration paper has small logo as proof.) License plate scanning, integration with registration database in the works.
@eff I wonder how resistant they are to false reads? That is, park a screen in its view, then display a series of computer generated license plates.

@eff this guy has some interesting articles. Search his name and ALPR. He been writing articles about it in Canada for almost 20 years.

@eff I can understand using it for finding a currently sought vehicle, but if its not a match, the data should be erased within a day to protect innocent citizens.
@eff polarized plate covers?
@eff The Village of Indian Hill, Ohio (near Cincinnati) has deployed Flock cameras. Pretty frustrating.
