You're never going to see the government walking in the door modifying source code. Those are tales they tell ppl. They are going to just blackmail someone or make some poor kid believe he/she can be a hacker by slipping backdoors into the software.
Does anyone recall the person who got a call in the middle of the night from the 'FBI' requesting a source code handover?
Yup. But I thought it was the NSA for an encryption program?
