In the grim darkness of the future there is only the space police, and lots of criminals to arrest. So how do you subdue someone in microgravity?
Do you tell them to put their hands up? Maybe. The whole idea is that it puts one's hands further away from the waist and chest, where weapons might be concealed, and in order to attack someone with one's fists one needs to place one's hands in front of one's torso before one can punch or grab the arresting officer (not that punching would ever be useful in microgravity). But if your hands are up, then that means you're not controlling where your body is, so you'll be floating around until the arresting officer can put the bracelets on.
Would you handcuff them? It certainly would prevent one from using one's hands to resist or interfere with the arresting procedure. Someone who's skilled might be able to move around with only their legs, but most people would just hurt themselves if they tried pushing around without the use of their arms to prevent collisions.
If you want to pat someone down (if you're in a pressurized environ—a space station or an asteroid base—the inhabitants would largely be wearing normal clothes) for weapons then either the suspect needs to be very cooperative by keeping himself steady with a handhold, or you need a second officer to hold him still while another officer gropes the suspect.
Is there a better way to arrest space pirates? Or do the space police need to suffer the traditional techniques in order to bring in the bad guys?
