When two white males accidentally bump into each other on the crosswalk, they would simply shake it off or say "Sorry/Excuse me"
When two black males 'accidentally' bump into each other on the crosswalk, they would start a fight right then and there for the littlest reason. Heck, one might even pull out a gun or knife. ...Maybe both.
