Besides the fact that if you do get shot doing something STUPID by a police officer, it is almost guaranteed you will be charged with a crime. The OP made a wise choice which should not be confused by gobbly gook that might lead him to make a mistake the next time. Or anybody else that might read such stupidity.
You seem to remain under the illusion that stupidity is against the law, it is not.
Your effort to pretend that touching the firearm would have violated the law is null, in pure argument stance, without any doubt, since the officer was indeed within the law to take possession of the firearm, the citizen failed to follow a lawful order which is also against the law.
Again, you can argue all the bs you like but the facts will remain and the op's question has not changed. A firearm in plain sight and within reach of a suspect during a legal detainment may be taken control of by an officer without recourse against that officer for doing so. While I agree with your thoughts that the method the officer attempted to do so was a poor method, however; that does not make it illegal just because you want it to be.
Brandishing is a catch all in many states and remains undefined in MO, however it falls under a more common and opinion based phrase in many of the laws as "handle a firearm in a "rude or angry manner" for the assault charge.
While most officers would state they would indeed not want the citizen to touch the firearm, your thought that the police officer asked the citizen to hand him the gun and place it on top of the car so he could draw his blaster and shoot him is some serious paranoia on your part and poor procedures on the officers part, neither of which fall under a category of criminal behavior or a civil action as the thread has implied.
