If I may I'd like to make a couple of observations about visiting the USA - something I do on a regular basis.
The fingerprinting thing takes about 5 seconds. It's really no hassle and it ties you to the passport you produce. If that cuts down on crime in the US I see it as a nuisance, but no more. At least an effort is being made to tighten up their procedures so that they know who is visiting and who is leaving the country.
As for the welcome, in 9 cases out of 10 the welcome I have received has been polite and warm. Yes there has been the odd officious jobsworth, but have you been through Heathrow lately? And frankly, we don't have a clue who holds a UK passport or who is in our country. Thanks Mr Reid.
Once in the country I find Americans to be almost unfailingly polite, friendly and helpful. Try shopping in London and see what kind or response you get.
