SRU cant patrol

[Haarek]

not looking out for speeders and jaywalkers.

No one said they should be.
Just because a SRU is patrolling doesn't mean they're doing the same job as a police officer.

If a SRU was to see something while they're on patrol they can call the police to investigate the situation.
It just puts more eyes and ears on the street.

It's like if a police officer sees a weapon they call the SRU, so if a SRU saw something minor they would radio the police to look into it.

Dude how often do you see a freaking SWAT team patroling the streets? 

Police can handle firearms, but not heavy gun fights. Thats the part where the SRU has it duty to do

If the president was to order the SRU to go out in the city to control and prevent malicious activity doesn't seem wrong to me.

RIC0H has a very good point.

Simply placing armed personell somewhere will prevent lawbreak (specially in real life.)
And I don't see how that shouldn't be allowed. 

And OFCOURSE they will not be patroling like a real officer unless it is obvious that they should stop what is happening Etc. 
If someone is speeding or whatever they will inform police officers.
