Cantwell - Is He a Federal Agent?

Rlyi thinks we've only seen one of the defendants on the stand, so far. I have a strong feeling cantwell is going to use every opportunity that he has his fr enemies under oath to ask them if they snitched on him. It's hard to walk the line between getting a kick out of some of these moments where it ise genuinely funny, right? But, yo, remember, these people are very dangerous. These people are responsible for a death.
