Politicians, celebrities and civil rights activists have been sharing and touting #8CantWait, a movement led by Campaign Zero to enact eight basic police policies that have been proven to reduce police violence.

While the movement has gained steam in recent days due to the worldwide protests against police brutality, some activists have questioned whether the eight rules are effective, considering some cities with the worst police violence have already enacted many of them. 

According to the #8CantWait website, the eight policies include a ban on shooting moving vehicles, a ban on chokeholds and strangleholds, a requirement to use shooting only as a last resort and mandatory, comprehensive reporting by officers. The policies also include requirements that officers give warnings before firing their weapons and stop others from using excessive force.

The #8CantWait website includes an interactive component that shows users which policies have been enacted in their cities and provides resources for them to contact their mayors and ask that these policies be put in place as soon as possible. 

The initiative also suggests that limits be placed on the type of force or weapons that can be used in specific situations. 

The platform has been supported by Oprah WinfreyLupita Nyong'oJada Pinkett Smith and Twitter CEO Jack Dorsey. In an interview with GQ, activist DeRay Mckesson spoke about the difficulties with the policies.

“The hard part is this analysis and data is new and the first of its kind. And the police say, ‘If you restrict our ability to use these types of force, you make us less safe.’ That actually isn’t true. In cities where there are more restrictive force policies, the police are actually safer, and communities are actually safer. The police will also say things about crime being rampant if they can’t use force. That’s not true either,” Mckesson said.

Brittany Packnett Cunningham, the co-founder of Campaign Zero, wrote on Twitter that these eight policies are being pushed because they can be enacted without legislation or executive orders.

#8CantWait has been trending on Twitter over the past few days due to a number of high-profile actors and activists pushing the movement. 

But, some have raised questions about how the rules can truly be enforced when police departments that enacted some or all of them, like those in Baltimore, San Francisco and New York City, continue to circumvent them. Some have also noted that police already break many of the laws limiting their actions anyway.
