but, how often is it enforced?

i mean, it's discretion, right? and, if you're setting of red flags, anyways...

i answered the question truthfully, and they gave me a nexus card - because their discretion was that i'm harmless. and, so long as we're not at critical mass for an imminent anarchist revolution, in which case all bets are off, they're right - i am harmless.

so, this is kind of throwing a rock at a hornet's nest. there's not much chance of anything good coming out of it.
