After following the situation after two days, here is what comes into my mind:
The riots widespread and extent over the last 72 hours, there has been attacks in the mayor commercial districts in different areas through the UK, and there have been fires and all kinds of vandalism over the areas in which the riots take place.
The police response took place over the normal protocols, but the riots seem too widespread into for the police to handle, now, what comes to my mind(and I know this will subjected into many political/social and other topics) is why the army hasn't been mobilized?
As far as I understand, the riots began under a peaceful protest, which created disturbances that created the riots, but the police response was kind too small due to the quick growing of the riots, what I think is that the army(or UK version of national guard) should have been mobilized 48 hours after first riot, since then the protest was no longer a protest that can be politically blameable, I don't understand really well how police response is or acts under situations like this(in a smaller considerable scale)and why the army or any other mayor law enforcement take control of this situation(and I know that Army=/= law enforcement, just so you guys get the idea).
The Americans deployed the National guard after the riots on LA, which can be consider of similar(not equal) scale, and while there was many subjections under under that, I consider that such actions provides damage control, something that UK seem to need at this moment.
