No. This country has always been charitable to those in need and long may it continue. It's sickening that this pair (if there are only 2), have thrown it back in our faces and I feel sorry for the old couple who must feel terrible when all they were trying to do was help, but we have never turned our backs on those in need and we never should.
Of course, if we can give the authorities more resources to police it better then I'm all for it.
Of course, in an ideal world, there'd be no war zones so people wouldn't feel the need to risk their families lives trying to cross the med in a dinghy.
And please remember, the two worst atrocities of recent years, London 7/7 and Manchester were carried out by British citizens and by a guy who was known to the authorities but had had a control order lifted so he could travel freely between the UK and Libya to help moderates, (that's Al Queda and ISIS to me and you), fight Gadaffi. So policing refugees is only one part of the issue.
