It's legal: cops seize cell phone, impersonate owner
"In November 2009, police officers in the state of Washington seized an iPhone belonging to suspected
Prohibited Subject. While the phone was in police custody, a man named
Prohibited sent a text message to the device, reading, "Hey whats up dogg can you call me i need to talk to you." Suspecting that
Prohibited was looking to buy
Prohibited from
Prohibited Topic, Detective
Prohibited replied to the message, posing as
Prohibited. With a series of text messages, he arranged to meet
Prohibited in the parking lot of a local grocery store—where
Prohibited was arrested and charged with attempted possession of
Prohibited subject."
