Gentlemen, I understand the questioning about the gun needs to stop but this was not the main issue as I saw it. Would you not, if it was your job to enter a potentially deadly situation and figure out what if ANY crime is being committed control the obvious means to your injury or death? (take control of the "suspect's" firearm) until you know what is going on? Once you have found out that no crime has been committed then return the gun to the owner. Being a prick about it "well you don't know me but I'm angry and you can't take my gun" is not going to help the overall situation. They are not trying to take you gun and say your a bad person but control the situation and find out if there is a bad guy you just don't know from there position right away. Did the officers handle the situation poorly? Don't know I wasn't there.
No, there were multiple units on scene, there's no reason that one officer couldn't investigate (talk to the wife) while another officer (or multiple officers) keeps an eye on the subject.
