The amount of police that were seriously injured was crazy high, and I can't imagine anyone that appreciates putting themselves in harms way and barriers to effectively doing their job.
I have the utmost respect, probably even more so than any police force elsewhere, for the officers that have to try and enforce the law with so many hurdles and so little support and tools at their disposal. They have cojones.

So I didn't mean to imply its the cops fault, but the legislators and the people that support them that are continuously soft on crime. Now I haven't stayed in the UK very long and its been years, but generally speaking I think most don't appreciate how soft they are until they visit Texas for example. I think the culture shock would have stopped those thugs in their tracks INSTANTLY, and the twitter feeds instead of "OMG, so much fun, lol! share your loot stories! woot!" would have been "dude, don't go out unless you want to get teargassed, shot with beanbags, have a permanent criminal record, and spend the next month in jail trying to protect your rear end from bigger inmates".
I mean, cmon, they even firebombed police HQ! That is a complete and total lack of respect for the authority of the police to do anything to them.
