After a volunteer confirmed an officer’s identity, they would alert neighbors to the agent’s presence, and our dispatch team would send a text message to our contacts in the area. ICE agents almost never carry judicial warrants giving them the authority to enter private homes or businesses without permission, so they often wait to make an arrest when the person they’re looking for leaves their home or car. And in every case we worked on, when the agents realized they were being watched, they abandoned their stakeout.
Provide me a method to distinguish your sarcastic statement from one out of someone who genuinely doesn’t know how easily SMS can be tracked, or a troll, or disinformation, and then I’ll accept your “of course”. As far as I’m aware there’s no way to be sure without asking; relying on a statements ridiculousness to reveal it as sarcasm is a losing strategy in the post-truth world.
