Such as ... a firecracker? http://online.wsj.com/article/APf231ddf494624e9c90bf3cd27057afc0.html

Or guns filled with blank rounds? http://en.wikipedia.org/wiki/Jon-Erik_Hexum

Or a starter's pistol? http://www.ncbi.nlm.nih.gov/pubmed/2275462

Or non-explosive? In 2007, 2008 and 2009, a total of 124 people, including 23 children and teenagers aged 18 and younger, were killed in Texas from accidents involving BB guns, pellet guns and other types of firearms that do not use gunpowder, according to data supplied by the Texas Department of State Health Services. http://travel.nytimes.com/2012/01/09/us/teenagers-death-a-reminder-of-gun-replicas-dangers.html?pagewanted=all&_r=0

You can't legislate against stupidity, nor against a man devout in getting his crime committed -- especially if he's willing to sacrifice himself either legally or physically in the process.

More legislation is not the solution. Love, attention, education, and a proper foundation of faith is always the solution. And for those to which it's not the solution ... there is no solution for those people (and that includes additional legislation).
