To make a warrantless arrest for a Class D or E crime, the crime must be committed under which condition?

For a warrantless arrest to be valid in the case of a Class D or E crime, the crime must occur in the presence of the officer. This requirement is grounded in the principles of immediacy and the ability of the officer to take action based on direct observation of the offense. When an officer witnesses a crime, they can make an informed decision to arrest, which eliminates the need for a warrant, as they are acting based on firsthand evidence of the illegal act.

This requirement is designed to ensure that the rights of individuals are respected while allowing law enforcement to respond promptly to criminal behavior. If an officer did not witness the crime, they would need a warrant based on probable cause to make an arrest. This principle helps to maintain the legal standards of arrest and due process, ensuring that actions taken by officers are justifiable and legally sound.
