Obviously, police officers have probable cause to arrest in light of such flagrant traffic violations. The propriety of the arrest is confirmed by the fact that Krueger pointed a gun at Officer Zahn after the stop. Because of his behavior, Krueger was a danger not only to himself but the community. Officer Zahn certainly had constitu- tional discretion to arrest. Police officers, however, do not commit constitutional violations by failing to follow the tactical advice of non-police officers.
Police officers have discretion to arrest even in contravention of such advice.
Officer Zahn had good reasons to arrest Krueger. Finally, Krueger argues that Chief DeQuaine violated his constitutional rights by failing to properly train and supervise his officers. Although his brief does not clear- ly state his legal theory on this point, apparently Krueger believes that Chief DeQuaine should have instructed the Algoma police officers not to arrest him on the occasions when they reasonably believed he was violating the law. Of course, no police chief is under a constitutional obliga- tion to give such an order. Somehow tied to this theory is Krueger's complaint that the police department violated his rights by releasing him into his mother's custody af- ter he had made a suicide threat.
