Legal Question

The times they are a-changin’.

This post seems to be older than 18 years—a long time on the internet. It might be outdated.

Watching Third Watch: “Officer Involved” on A&E. The PD finds this kid who is stuck between two walls and they call the FD to come get him out. The FD has to break into a locked garage to get access to a cement wall. While the FD is cutting into the wall to get the kid out, the owner shows up. The FD eventually gets the kid out, however the PD finds a stash of pot in the garage.

Can the PD arrest the owner? Why or why not?
