“Denver police, who were visibly present in the area, did nothing to stop the attacks or to allow the peaceful pro-police rally to continue.”
They follow the orders and do the bidding of the names that have their signatures on their paychecks. Almost exclusively in cities in America, even in Red States, those are names of leftist Democrats. Sheriffs departments, often elected, are a different beast. But looking for help from those whose paychecks and pensions are controlled by far leftists, is not wise.
