Protests continue in Wauwatosa, Wisconsin, and 28 arrests have been made. The Police Department warns they are seeing the force escalate.

This is the fourth night of protests after a grand jury declined to indict the police officer who shot and killed 17-year-old Alvin Cole.

The Associated Press reports police used tear gas and arrested 28 people on Saturday.

Protesters were in violation of the 7 p.m. curfew.

The Wauwatosa Police Department tweeted on Saturday afternoon, “Over the past three nights, we have seen an escalation in force by the protesters.”

The Wauwatosa Police Department said that people were asking questions about their responses over the last three nights. “For example, why are we concerned about bottles being thrown at us?”

They explained, “These materials (bottles with flammable fluids, toilet paper, and lighter fluid) can be used to start fires. This is also known as a Molotov cocktail.”

Breitbart Texas reported that Milwaukee County District Attorney John T. Chisholm said on Wednesday, “I do not believe that the State could disprove self-defense or defense of others in this case and therefore could not meet the burden required to charge Officer Mensah.”
