Hmmm, this may fall under the category of a "home invasion". Gangsta Mouse invaded Mr. Katz domicile intending to cause harm to Mr. Katz or his property. Mr. Katz was completely within his rights to protect said property with all the weapons at his disposal. It is unfortunate that Gangsta Mouse had to pay the ultimate price but he entered Mr. Katz home looking for trouble. Yes, Mr. Katz should have alerted the authorities before taking matters into his own "hands" but it appears his alarm system was malfunctioning or that those responsible for responding to the alarm were negligent in their duties. Since this is the American Justice System we're talking about here. I suspect that Gangsta Mouse's "homies" will win a mega-million dollar settlement against the alarm system company and its agents. See Gangsta Mouse isn't responsible for his own actions -- he was high on sugar from the marshmellows he ate. Yeppers, it's the alarm system's fault.
