Due to this incident the military was heavily limited in how they could help the police

Later the laws changed again to allow the police to get some help from the military but only in very specific cases where the police were the one in control of the military (the police could order the military what to do, and not the opposite).

I think they can help with transports and such but I don't why that is needed.

If I remember correctly the government is trying to change the laws regarding this.
