What situation could lead to an immediate arrest without a warrant due to a felony?

An immediate arrest without a warrant can occur when a felony is committed in view of an officer. This principle stems from the need for law enforcement to respond promptly to crimes in progress or those they directly observe, ensuring that justice is served and potential further harm is mitigated. When an officer witnesses a felony, they have the authority to make an arrest on the spot, as they are able to corroborate the crime firsthand and assess the situation immediately. This immediate response helps to uphold public safety and maintains the rule of law.

In contrast, the presence of a lawyer may suggest that legal representation is available, but it does not provide grounds for immediate arrest. A signature on a document could pertain to various administrative matters but does not relate to the nature of a felony committed in an officer's view. Notification from dispatch might inform an officer of a situation requiring attention, but it does not replace the firsthand observation that warrants immediate action.
