I just watched the classic movie "High Noon," AGAIN! Gary Cooper played a brave sheriff who brought law and order to his town. As one woman said, "He made it safe for a decent woman to walk down the street". A recently released outlaw was coming back to town on the noon train to deliver vengeance against the sheriff who put him away. His gang of three arrived early to help their leader take out the sheriff. Fully aware of why the bad men were in town, the sheriff could not arrest them because they had not broken any laws. Waiting is not illegal.
