In ways of riot teams, most departments do not see riots enough to designate units for that sole purpose. Most departments, such as the Royal Nfld Constab, or the RCMP in BC will often enlist buses, and other non-emergency vehicles to bring in the people. If a riot mission were to be planned, we'd be looking at something similar to that, a civil bus made to bring in 30 cops or so, but to my knowledge there isn't one planned at this time
As for the Pointy lightbar, I've seen them in use, they look weird, yes, but remember what everyone was saying when people were making the switch from the big rotatory bars to LED. It's just because it's new and strange. It does work wonders.
