C.R.A.B Droid could join the police force

Could the C.R.A.B (Cybernetic Autonomous Remote Barricade) Droid robotic sentry system designed by Jamie Martin strike fear into the hearts of baddies everywhere if it ever becomes realized in police departments worldwide? Perhaps, but there is also the risk of the bad guys hacking into the system and taking control of C.R.A.B. for their own nefarious purposes. While there is no foolproof plan when it comes to stopping crime, a strong deterrent always helps, although this concept might not just be too practical.
