Hi Simba, Please see below for my corrections. Neither of them sound natural to me - it may be due to the higher level words however: 1. Is the violating laws against interfering with an officer in the act of duty applies to K9 in the U.S? Better as: Does violating the laws against interfering with an officer in the act of duty apply to the K9 unit in the US? 2. Would a suspect be accused of obstruction, if a suspect assault on K9 in the act of duty in the U.S? Better as: Would a suspect be accused of obstruction if they assaulted a member of the K9 unit whilst they were on duty? If you have any questions, feel free to message. Hope that helps. Good luck with your studies. Alice

Thank you. Ashli.

I would probably word them a little differently (I hope I understood what question you were really asking) 1)Does the law violation of interfering with an officer in the act of duty apply to K9 units in the U.S.? 2)Would a suspect be accused of obstruction in the U.S. if they assaulted a K9 unit in the act of duty?
