2. Excellent advice.

One uncommon tip in the post above is Never talk to cops. Years ago a friend of mine, a guy who was employed but not earning enough to pay rent and therefore homeless, was ticketed while riding a bike in Beverly Hills.

His real "offense" was asking a police officer a friendly question -- while looking very scruffy and riding a bike.

The police are not there to talk to us. At most you can ask directions -- very politely. Other than that, let them focus on their work. If they become hostile, remember they are human beings who can make mistake and that their mistakes can have very serious consequences for you because they are armed (you probably aren't) and they can arrest you (obviously something you probably cannot do right then and there).

Generally, the advice in the OP is really great.

Not trying to talk to police officers, however, is so important and not often mentioned. Thanks, Fire Walk With Me.

Also, I really, really like this:

"f someone starts discussing being violent, walk away. If someone starts being violent during a march, immediately step away from them."

Violence accomplishes nothing. It just invites more violence. So walk away from discussion of violence. Don't even joke about it. It isn't funny. People get hurt. If someone starts being violent, I totally agree, you should get away from them as quickly as you can. Let the police sort them out. Don't waste your precious time. Don't join them. Only peaceful protest really works.
