§ 1229 Execution of search warrant - Liberating person detained.

Here's a plain English summary of this rule:

If an officer is carrying out a search warrant, the law allows them to break open doors or windows in certain situations. This applies if someone who came in to help with the search gets trapped or held inside the house. The officer can force their way in to help that person get out safely.

The rule also covers the officer's own safety. If the officer themselves gets stuck or trapped inside while executing the warrant, they have the legal right to break open doors or windows to free themselves.

In short, this rule gives officers the power to use force on doors and windows, not just to get into a home, but also to get people out when they're trapped during a search warrant situation.
