The police definitely need to intervene, but I'd like to think that playing tit-for-tat with the government is a valid protest, and that this won't result in a loss of freedom.

I guess they need to ascertain whether he's operating organically, or at the behest of another nation, and whether he's scouting out ministers for something bigger in the future.

Though, the irony in all this, is that it all could've been avoided if the government weren't acting at the behest of another nation, and scouting out what they can get away with on their authoritarian warpath. Maybe the police are arresting the wrong people.
