Yeah, I'd just make a new profile, one where I'm constantly being sent messages thanking me for running that marathon for charity, and thanking me for saving that drowning child from a river and donating a spare kidney for a terminal patient, and stopped an armed robbery at my previous employers single handed and unarmed.
Then I'd by all means hand it over.
Or, alternatively, I'd go apply to a company whose management layer is not entirely staffed by clueless yet malicious DICKS.
As for McCullen, the problem with his attitude about privacy, is that he's in a very special situation, he both knows that he's a ****, and doesn't care if everyone else knows. Most normal people, if they'd done even one of the terrible things he has, would try to hide it and feel bad about it, not gleefully revel in being so despicable, he's like some kind of movie villain.
At least some of the people caught in the Leveson enquiry have had the humanity to be shamed about the things they've done to keep a job.
He thinks because someone's had a child abducted and murdered, they're suddenly 'celebs' and deserve to have him in their garden rooting thru their bins in the hope of finding porn or drugs.
EDIT: also, privacy is important when you know you can't for a moment trust that anything reported in the tabloids will stick to the facts. Say for example, Justin Bieber's bin has a cold remedy packet in it, that's enough for the headline 'Bieber in teen drugs binge shame', then about 4 paragraphs down mention that it was entirely legal drugs. If you're not sure that's enough, just write that he's probably abusing them to get a 'legal high' and you've got another page of shite to print.
Not that I like him, but I'd defend Bieber over the UK tabloids any day.
