Wright v. D.C., just filed today, is a Second Amendment challenge to D.C.’s stun gun ban; the case is being litigated by lawyer George Lyon, who was one of the original plaintiffs in the Heller handgun case. Here is a summary of why the named plaintiffs want to have Tasers; I think it’s a very good explanation of why restrictions on Tasers are serious burdens on self-defense, even when handguns are legally allowed:
Plaintiff Crystal Wright is an individual who is outspoken on political matters. She operates a blog on the Internet under the name “Conservative Black Chick.” As a result of her blog posts, she has been threatened with physical harm. One person sent her an email saying that he intended to break into her home and bash her head in.
Ms. Wright has been trained in firearms and contemplates obtaining a firearm to protect herself in her home in accordance with District of Columbia law. She is ready, willing and able to use deadly force to defend herself and her home from a potentially lethal attack, if necessary and unavoidable.
