Well, the Home Office have recently been consulting on the provisions of
PACE 1984 ... you'd presumably want to see s18 removed

the power extends to premises which are "occupied or controlled by a
person who is under arrest for an arrestable offence"

yes ... but you're back in the realm of what Ian Batten helpfully called
"law abiding criminals".  Many searches of company computers are carried
out with the help and assistance of the company and/or their sysadmins

the search warrant from Kent is perfectly good in Kendal (and in
Cardiff)... whether it is good in Kirkcaldy I'm unsure (I believe
probably not)
