Even in self defense, our actions are still going to be under the microscope.
There's a thread on this Indianapolis area incident elsewhere on the site:
Prosecutor: Fatal attack was justified
Robert McNally will not face criminal charges in the death of David Meyers, Brizzi said in a statement.
Meyers, 52, climbed through a window and tried to assault McNally's 17-year-old daughter in her bedroom at about 3:20 a.m. Sunday, police said.
McNally, 64, was awakened by the girl's screams and struggled with the attacker, putting him in a fatal chokehold, police said.
Meyers, a convicted sex offender, was nude except for a mask. He carried a rope, condoms and a knife, police said.
Lengthier stories made it apparent that the father had not used a chokehold as we understand it but was laying on the intruder, holding him down with an arm around his neck. When the police arrived they had to tell him he could finally let go. The autopsy indicated that the intruder's heart disease contributed to his death.
A few days after the attack, but before the story above, this story was the front page headline in the Indianapolis Star:
When deadly force is justified
Advocates say laws protect the right to self-defense, but opponents fear they encourage violence
The story doesn't explicitly quote people calling for the father to be prosecuted, but indicates that there are those who oppose the law that shields him from prosecution.
So, theorize all you want, folks...but a 64 year old man in his own house defended his daughter from sexual assault against an armed man who was a convicted felon, using only his hands. The felon died from the man's actions and his own pre-existing heart condition, and some people think the law that protects the homeowner is too broad. So if you think you're justified in bashing a man's head in on the street, be aware that there are people (and jurisdictions) that disagree. It doesn't matter whether you think that's right or not.
