True or False: A police officer may arrest a person believed to be trespassing without a warrant.

A police officer is empowered to arrest individuals believed to be committing certain offenses without a warrant under specific circumstances, including trespassing. In many jurisdictions, this includes situations where the officer has observable evidence of the crime taking place or if they are in the vicinity and witness the act of trespassing. This power is rooted in the principle of maintaining public safety and preventing ongoing offenses.

If an officer sees someone unlawfully entering or remaining on property where they do not have permission, they can take immediate action to prevent the behavior and protect the property owner's rights. This ability to act without a warrant is particularly important for addressing crimes that may be continuing or escalating at the time of the officer's observation.

The other options suggest conditions or limitations that do not typically apply in this context. The power to arrest without a warrant for trespassing is generally straightforward, focused on protecting property and deterring further wrongdoing.
