NYPD Anti-Terrorism Cameras Used For Much More
An anonymous reader writes with an excerpt from the NY Times:
"The Police Department's growing web of license-plate-reading cameras has been transforming investigative work. Though the imaging technology was conceived primarily as a counterterrorism tool, the cameras' presence — all those sets of watchful eyes that never seem to blink — has aided in all sorts of traditional criminal investigations. ... 'We knew going into it that they would have other obvious benefits,' Mr. Browne said about the use of the readers in the initiative. 'Obviously, conventional crime is far more common than terrorism, so it is not surprising that they would have benefits, more frequently, in conventional crime fighting than in terrorism.'"
The Law of Unintended Consequences will probably come into play here. As camera systems - especially ones mounted on cop cars - get better at reading license plates, law enforcement officers will probably come to rely on them more. I.e. they'll pay less attention to your plates. So one conclusion that might be draw from this is that if you hide/obfuscate your plates, you're more likely to get away with it.
SCOTUS ruled that use of public roadways is public knowledge and legal without a warrant, including the use of GPS tracking units on your "private" vehicle. Their ruling is that when driving on a public roadway, there is absolutely no expectation of privacy as to your travelling.
Nope, SCOTUS has never ruled on the requirement or lack there of in obtaining a warrant to utilize a GPS tracking device on a private vehicle. More specifically, the circuit courts are split on this topic with the D.C Circuit court in Commonwealth v. Connolly mandating a warrant and the Ninth in USA v. Juan Pineda-Moreno writing carte-blanche to track anyone anywhere.
But perhaps you are confused with USA v. Knotts in that SCOTUS did decided that the monitoring of a pager embed in a barrel of chemicals that the defendant was using to manufacture methanphetamines was A-ok. The DC courts did take this SCOTUS decision into account and came back with a decision that a pager was only good for a day or two max, but the GPS machines could last for months.
Now, searching inside the vehicle, that's a different question. And what if the camera takes a picture through your windows?
Yes, indeed a search of a vehicle is a different topic all together. However, the plain view doctrine would most definitely allow pictures that reveal the contents of your vehicle from a vantage point outside into the court of law.
