I remember I saw a film, it was probably set in the UK in our times, produced probably by US or/and UK, released maybe between 2010-2014, maybe earlier or later. I’m almost sure it was played in cinema, but I saw it on the Internet. There was a group of men, probably some active of former police officers. The scene show one of the men, holding some other guy behind him (he could be their target to kill or someone like that) and another man from the group was aiming with gun at the hold guy and he was being told not to shoot because he could have also killed his friend if he would’ve shot. Unfortunately he take a shot and killed both men. I think I also remember some scene in a bathroom, where some other guy was killed, but I don’t remember the details.
