History

The history of crowd control starts back in the 1920s, where there was no official crowd control unit. There would be ten to 20 officers lined up. Behind one line there would be another line about twenty feet back. The officers were armed with
batons and

handles. Their job is to simply hold the crowd back, which would end in a free for all and resulting in multiple officer injuries.
Later in the 1950s, the first actual riot control teams armed with riot shields and batons appeared; the goal was for the riot shield officers to hold up the lines. When they came to actual contact with the crowd, the officers with the batons were supposed to help the riot shield officers. However, if deadly force was used against them, there was no training or procedure to counter this causing the officers to have to fend for themselves.
The 1960s and 1970s marked the invention and widespread use of the
tear gas

. However, with this new innovation the officers were not used to operating in an environment where visibility was limited. The armor that they wore at the time was not as mobile. This resulting in that type of armor being rarely used.
A crowd controller is also another name for a
bouncer or
doorman.
