I don't think people understand what arms dealers really do. They invest thousands of man and computer hours into designing killingry which people are willing to pay lots of money for. As a business, they want to keep their customer base happy, which means allowing their customers (yes, presumably the NSA/FBI/etc.) to use their weapons rather than not selling them. Yes, it's probably the case that these weapons don't just go to nabbing child pornographers or drug traffickers, they also probably try to catch the next Snowden, which not everyone agrees is The Right Thing To Do. But for what it's worth, I'd still trust the US government (even with all its faults) far more
