Why do they disrupt inside the building?

If the venue can hold 10,000 people, and contempt for the candidate, why not gather outside the building with 20,000 people. A Gandhi type protest.

Wouldn't it be a more effective non-violent strategy that sends a more accurate message that they are not the party of hate?

As a result even more protesters would show up knowing there was a reasonable amount of certainty there wouldn't be violence. Just like a lot of people wanted to see the Stones for free at Altamont but not if the Hell's Angels are security.

As far as who should arrest who, one would think mayors, police, security guards and secret service know their job and roles better then anyone else.

ok--I'm going to put on my flak jacket now. OK, I'm ready.
