No violence is justified, not even in retaliation, not even if Trump encourages it....not even if a Trump supporter sucker punches in the face a man handcuffed and being removed, and certainly not people just leaving the venue who have a trump hat on...no matter what Trump encourages by having his rallies in the most Democratic city in California, next to a college, with the majority of residents Latinos....no one should let him set them up for a fight....
Level headed people don't resort to violence... Sticks and Stones may break my bones, but Names will never hurt me.
And ALL of those people who resort to egg throwing and hat stealing and intimidation in San Jose' were wrong, no matter what Trump has said and implied about them, and all the Trump supporters that resorted to violence and sucker punches against the anti-trumpsters were wrong...even if Trump encourages it and offers to pay their lawyers when arrested.
Trump had a bad week, with his bigotry against the judge in his Trump U case and Veteran charity distribution....Hillary's speech using Trump's own words showing how he is UNFIT to serve was just the icing on the cake...the polling is reflecting this... it will yo-yo a hundred times before the election... with each having their bad weeks in polling.
