http://www.state.il.us/court/opinions/SupremeCourt/2012/112948.pdf See especially section 45 and on. Sorry the kid was hurt, but this is the correct response- Personal and parental responsibility.
I am sorry to hear the kid was hurt permanently for the rest of his life. However, I totally agree with the courts ruling. I hate it when I hear that some trespasser or someone that does some clownish act (ie the woman who sued McDonalds for burning herself with coffee) and ends up getting award a sum of $$$ for their own stupidity.
See what happens when you play with Trains???? Another reason why boys are soooo stupid around girls. How hard is it to understand NO TRESPASSING? Glad to hear the outcome of the jury.
