Boston Police Department Commissioner William Evans told reporters on Saturday that leftist protesters hurled bottles full of urine at the police.
This was tweeted out by the Boston Police earlier.
#BPD is asking individuals to refrain from throwing urine, bottles and other harmful projectiles at our officers.

The commissioner then attacked the free speech protest organizers.
27 leftists were arrested.
The President condemned the alt-left violence today.
Looks like many anti-police agitators in Boston. Police are looking tough and smart! Thank you.
