I'd wait for him to try and break in, pretending to be asleep, then jump him and K.O. him with chloroform. THEN i'd call the police and get them to come over. Seeing the serial killer, i'd say "IS THAT ENOUGH PROOF FOR YOU, FUZZ?" And let them take him away.
I would kill him after making him relive every single moment of what he did to his previous victims. I think that would be poetic justice. I dont beleive in taking lives, but I would make an exception in that case. Quid pro quo, ya know? I dont think anyone would mind.
c4 all the doors and windows. first sign of trouble BOOM blow the crap outa the place. well....maybe haveing them all set on one remote might be bad..... then i would get a shovel(shovels always work in horror movies. and chainsaws......)
It's a joke. Exempt the shovel and chainsaw stuff that's true. But the c4 stuff would kill him right? And it would save others. FOR THE GREATER GOOD *BOOM*!!!
