Similar to the other thread, what do you find to be the worst police “uniform-isms”?

A commenter on the other thread inspired me to post this question. I often see colleagues wear or modify their uniforms in ways that to me, just look stupid or them trying to be tactiCOOL.

The main two for me are (i) tucking trousers in to boots and (ii) buying your own custom name patch with “PC 1234 (name)” or similar.
