No need to have a empty holster on your side,,,kinda like taking an empty Glock mag in to a court house. Why bring attention to yourself? I know you just wanted to make a big deal out of it. If so you could have told him your ride dropped you off and you have no car to put it in,,,he prob would have told you to cover it or put it on a pocket(if you wanted to "try" the police). Sure there is no law against a empty holster so next time push it or leave it in the car with the gun. There is no law against pens(stabing object) or a comb( NASTY cutting object). You can also have a brick,,no signs about them(yet).
