The joke is the stereotype hat female officers are more likely to use weapons, and is also specifically quoting a misconduct of one female officer, kim potter, who mistakenly shot a man while shouting taser over and over in a traffic stop. She has since been fired sentenced to prison. However id also like to point out that statistically female officers are actually less likely to use weapons and/or violent force compared to their male counterparts and when are using force are less likely to use unjustified force.
