honestly I think that RTO's should fill in their roles a lot more than they are doing currently. most raids I have been in the normal officers create perimiters while RTU runs in with the others to shoot people down. I have close to never seen RTU do any traffic redirections during raids. yes they know how to take out vehicles in a high speed persuit, and their super fast vehicles makes them respond to certain situations really fast, but I believe that RTU should make their officers focus on the Road Traffic bit more rather than make it a more extended version of patrol.
I have not only come here to just point out issues, I'll give some sollutions aswell. You can make policies giving RTO's more specific things to do during raids or you can withdraw the weapons from only the officers so they are like the Traffic enforcers how they used to be.
but that's my honest opinion on it, do with it as you may.
