Blast,

Be mindful of the events and "emotional temperature" of what's going on around you.

If things start heating up, get the heck outta the way as fast as possible.

Yeah, they may be speaking french but an angry face and a clenched fist is universal.

Riots from what I've seen on TV, etc don't spontaneously spring up, there is an escalation of tensions and behavior.

From the riots I've seen on TV and the internet, there's too many actual or potential adversaries on a 360 degree front to effectively defend against, not to mention being collateral damage from indiscriminately launched rocks, beer bottles, poodles, teargas canisters, rubber bullets, etc.

I think it's best to bug out or find something as close to a fox (or gopher) hole to hide in until it is safe to bug out (or continue working).

Be careful, but have fun.
