A 68-year-old black veteran with a heart condition gets killed by White Plains, NY police officers when they respond to a distress call by a medical alert system. The police appears to argue that officers felt attacked and responded in self-defense.

• They came to his house after a medical alert call.
• He didn’t want them there and asked them to leave.
• They broke into his house.
• They hit him with a Taser.
• They saw him grab a knife (and by now I’d grab a weapon too, heart condition or not).
• They shot him in the chest twice, killing him.

Why, why, why? There are so many things wrong with this, how can a nightmare like this actually happen?
