I live in a country with very strict gun and weapon laws , where people live that think it's a very good thing , for if they could ,..they get one and they would use it . I answer them : Do you want one , for 500euro i have one tomorrow ? Clean and untraceable .
Funny how they never want one and are chocked that they so easily could . ;-)

If i had a metal workshop with the freedom to create , object accelerators would be high on my list .
