It’s unlikely that Clinton said that. The US, at the time, had tighter gun rules than most nations. Because Clinton, for most of his tenure, had little control over congress, he knew better than to thumb his nose at the powerful gun lobby. Mind you, the NRA always claimed he was aching to take away all the guns, but it wasn’t true. He didn’t have the power.
At what time was that? I can’t think of any country, under the rule of law, with less restrictions on guns than America. As for the OP, is it possible Clinton was talking about the Gun Control Act of 1968 while he was at university?
