Final answer:
The statement is false; police officers may use potentially deadly force in certain circumstances according to legal guidelines and policies when public safety is at risk.
Step-by-step explanation:
The statement that police officers are never allowed to use potentially deadly force (e.g., ramming a vehicle) to end a high-speed chase of a suspect, even if the suspect's actions risk the safety of other drivers and pedestrians, is false.
Police officers may be permitted to use such force under certain circumstances, following specific guidelines set by law and police department policies. These actions are generally considered when there is an imminent threat to public safety and other methods of apprehension have been ineffective.
The landmark case Terry v. Ohio established that police can stop and frisk a suspect if they have reasonable suspicion of criminal activity, and the use of force continuum determines the appropriate level of force in various situations.
