Partying bros harass ranger trying to keep Dolores Park clean (video) 'I don't know how you sleep at night, dude'

A group of obnoxious young men heap verbal abuse on two San Francisco park patrol officers trying to keep Dolores Park clean in a video last weekend posted on social media.

In the five-minute clip obtained by KRON, one of the officers tells the men to pick up their trash and

warns one that he'll get a ticket if he lights a cigarette as smoking is not permitted in

city parks.

"Dude, what a power trip," says an off-camera bro. "This a big ticket hard-on day? What's the

problem, man?" asks another.

The men argue with the officer about a table that he instructed them to move, a violation of

park code SEC 3.12, which prohibits household furniture or appliances.

That does not sit well with the partiers. "Stop making s--- up. You're making s--- up, dude," says

a member of the group.

Another attempts to point out that the officers were not accosting other people who brought

"household items" to the park.

"Blankets are household items," says one genius. "That's a household item. That's a household

item. Everything is a household item!"

Amid profanity, catcalls and insults, the officer's credentials are questioned.

"Are you an actual cop?" asks one.

"I don't know how you sleep at night, dude," says another.

The nastiest comment was made in reference to the officer's appearance.

"Maybe we should pay more (taxes) so they could get dental care," says "Brandon." Even

Brandon's fellow bros thought that crossed the line.

Throughout the encounter, the officer remains calm and professional despite being surrounded

by self-centered jackasses.

Neighbors and park workers say the crowds and the trash in Dolores Park have worsened in the past two years, in tandem with the growth of hipster and high-tech cultures in the Mission District.
