Many would argue that cops cross the line when they impersonate people on social networks to catch suspects, but that doesn't mean that fake accounts are always off the table. In a recent opinion, New Jersey district judge William Martini contends that police don't need search warrants to create bogus Instagram accounts for the sake of seeing a suspect's photos. As Martini explains, it's "consensual sharing" -- the perpetrator is both making these pictures public and willingly providing access to others. That's bad news for Daniel Gatson, an alleged burglar who insisted that law enforcement needed probable cause (that is, reasonable belief that there's evidence of a crime) to peek at an Instagram feed laden with shots of cash and jewelery.
