This is what happened with a Redditor, Sunday_Account, about six months ago.
Mr.Sunday_Account had a nice job with a company which worked for a federal agency.
The only thing about working with this company was the security clearances which Mr.Sunday_Account got.
I passed with no problem and about 6 months from the initial tool, I started working.
Everything as going quite well when one day Sunday_Account spilled coffee on his laptop and it went bust.
Being a miserly sort of man, he opened Craiglist to check for a cheap second hand laptop.
Pretty soon he found a random listing for a Samsung ATIV with i5 processor for $300.
Sunday_Account emailed the man who made the listing and he answered back.
Subsequently they agreed to meet up at a coffee house.
I met the guy at a coffee shop.
He was shaky; I mean he was crackhead shaky.
He was well-dressed but something wasnt right about the kid.
I saved $50.
Next day, our man had to attend a briefing on a new project at a new government agency.
He arrived at the agency and underwent the security screening process and all hell broke loose.
The next thing he knew was there were handcuffs in his hands and he was shoved off to jail.
He could get bail for three days however during that time he contacted a lawyer.
The lawyer believed him and cross checked with his colleagues.
He also had PI track down the guy who had made the listing on Craiglist.
It turned out that the guy who made the listing was a registered sex offender.
The $250 lappy cost him $12,000 in legal bills for the entire fracas.
