I am not sure what you're referring to but the strategy of delaying going to court is a may strategy used in US Courts. The state may have to be able to go to court within a speedy time but it doesn't stop the defendant delaying it.
Secondly, no the US protections are not stronger than the UK. The UK protections are that strong that if they don't get you to court in a certain amount of time they can't convict you. It's 6 months if you're held in custody and longer if you're on bail. It's quite common from my understand via documentaries of prison/jails that people spend a year in jail waiting for their trial and it's possible for multiple years if bailed.
