MORE FROM THE SAN JOSE POLITICAL RIOT: Trump supporters were ‘running for their lives’ after San Jose rally, police report says.

Two undercover police officers at a Donald Trump rally last week said they saw Trump supporters “get punched, kicked and pushed” and “running for their lives,” according to a police report.

The plainclothes officers said they did not intervene for fear their own safety would be jeopardized as the estimated 400 protesters developed a “mob mentality.”

The officers’ observations were included in the arrest report of Antonio Moses Fernandez, 19, of San Jose, who is accused of throwing a metal barrier into a police skirmish line following the Trump rally June 2 outside the San Jose Convention Center. Fernandez made his first court appearance Tuesday and was charged with felony assault on a peace officer with a deadly weapon and misdemeanor resisting, delaying or obstructing an officer, according to court documents.

About a dozen people were hit, some car windows were broken, and at least one woman was struck by a raw egg. Some Trump hats were torched after they were snatched from the candidate’s supporters. It’s unclear what role each of the men arrested allegedly had in the violence. In a statement, San Jose police said other people have been identified in connection with the violent demonstrations.”
