Re: "a very respectful way"
For anybody else jumping bail, then either:
a) they don't know where they are, in which case there's nowhere to stake out, although they will investigate. So they can't run a years-long stakeout OR:
b) they know where they are and they're in the UK, not in an embassy, in which case they just arrest them, so they don't need to run a years-long stakeout. OR:
c) they know where they are and they're outside the UK, in which case they will apply for the local police to arrest him and for extradition, but it's not their jurisdiction to run stakeouts.
So yes, Julian Assange is being treated specially, but that's because the wanted fugitive was granted asylum in a foreign embassy in the UK, which doesn't usually happen. The UK police know they will only get one chance to grab him, if/when he leaves the embassy to head for a boat or plane, and don't want to miss him (because that would be really bad press if nothing else), so they had officers stationed outside waiting for him.
There's no need to invoke conspiracy theories about them being out to "get him". The only people giving Julian special treatment are the Ecudorians.
