Code
Penal Code 148(a)(1)
When a public officer, peace officer or emergency medical technician carries out or tries to carry out their duties, and you willfully resist, obstruct or delay them in carrying out their duties. Keep in mind something like “delaying” can include many things. Deliberately giving incorrect or misleading information to an officer questioning you (e.g., a fake name) or getting in the way when an officer is arresting your friend are both examples of resisting arrest.
Consequence
Up to $1,000 fine and up to 1 year in jail
Takeaway
If you or a friend is in trouble with law enforcement, be cooperative with them to avoid extra fines.
