In the 1960s, the US government started cracking down on buying firearms. Bombings suddenly became rampant. In 1970, the US averaged more than a bombing a day. The government then tightened up restrictions on buying explosives further than they had for firearms, and Americans resigned themselves to going back to buying guns and shooting each other.
If the US government were to further restrict guns, people would notice that it’s easier to DIY a bomb than it is to DIY a gun, and that the former is also quite a bit more effective at making a point.
You can purchase everything you need to manufacture explosives in a supermarket.
“Same” is a valid response. I’ve never had an optometrist challenge it.
