It is a crime to file a false police report. When places of public accommodation enlist the police to remove people based on race, the owners and managers should be investigated and prosecuted for filing false police reports. At the Philly Starbucks, the Yale dorm, the golf course or the Oakland park, the police investigation should have focused on the frivolous and possibly criminal abuses of the 911 emergency system rather than on the people who were doing nothing wrong when someone called about them.
Civil law also provides ways to strike back at those who make 911 calls just to report the presence of a black person. Black people could sue callers for defamation or malicious prosecution — for reporting to the authorities that they’re “threatening” or somehow don’t belong in a space they have a right to be in.
In some cases, lawsuits could be filed for intentional infliction of emotional distress. Many state and municipal laws protect civil rights better than their federal equivalents; suits could be brought under these laws in some cases, too.
