Once read that it is very unwise to direct the output of a Nitrogen TEA laser (reasonably easy to build at home) into the sky during a tunder storm. The ionised channel will direct lightening to you.
It would make a great assination tool. Had nothing to do with me officer, twas a lightning strike.

Except for the part where you get killed instead of your target.

' to target President Obama and enemies of Israel '

“ Crawford has specifically identified Muslims and several other individuals/groups
as targets,” investigator Geoffrey Kent said in a court affidavit. According to the
indictment, Crawford also traveled to North Carolina in October to solicit money
for the weapon from a ranking member of the Ku Klux Klan, who informed the FBI.
