Posting as Involved. ( I was the one laying on the ground and the one you attempted to detain on your car )
As we all can see that you MG'ed THOM sms'ing him IC'ly about your roleplay and you didn't use any parentheses, that's the reason why Thom didn't take it as RP'ly and decided to roleplay that he's being cautious around and gazed at the surroundings, he saw you with a gun and shot you. END OF THE STORY.
-Up to admins if they will punish you for METAGAMING during roleplay scene.
