I was myself arrested on the 25th of September. My arrest is visible here. Through these means I was able to acquire the account from inside Western State Penitentiary. However, that is not the topic at hand.
According to the District Attorney of Pittsburgh, Pennsylvania, press credentials are only valid if they were cleared by the secret service for the G-20. Get that clear in your heads. The state, having arrested several journalists, is choosing to define what constitutes press affiliation based off of THEIR credentials. This is a fantastically blatant violation of the first amendment. It is, however, the official word of the Pittsburgh District Attorney’s Office.
