This talk of "sitting on a goldmine" is a shame. There are already too many frivolous lawsuits to go around, nobody needs another one. It seems perfectly legit for the guy to sue for medical bills, lost wages, maybe some mental scarring, etc. etc., and maybe just a couple grand for the trouble. However, to look at it as a "goldmine" and a way to just milk all the money you can out of the situation, beyond what you're realistically deserving of is pretty lame.
