I envision a day in the near future where robots are used to break into houses and make arrests. Texas has already done some "groundbreaking" law enforcement with robots.
I watched this happen the other day. Swat team arrived arrived at my friend's apartment complex in Austin. Turns out there was an armed meth dealer holed up next door. SWAT sent a robot in to scope the situation, find him, and then knew where in the apartment he was, so as to work out the safest entry point for the team. Was fascinating!
