Those lawsuits were claiming that tasr is not acutually non lethal, tasr guns were responsible for numerous death happened after tasr guns were applied, a lot of cases later turned out to be drug abuse, it was drugs that killed those people, I would say that those drug abusive people were already in a very dangerous situation, and a tasr gun may be the final "heavy" straw they can carry no more, Anyway, those lawsuits about death and injury made government hesistate to put in purchase order and tasr's growth suddenly dropped. Now tasr has won or dismissed nearly 50 similar lawsuits in a row, lose none, it looks like government order is accelerating, think about Chinese government, when Chinese government moves, they move all together at once, I do not know about US government, but moving in a herd is a human pattern, I would say. Think about stock market, real estate market.
Anyway, tasr was never cheap, even at $5 level, just that it has a huge potential being a monopoly, so be careful, if you want to buy, buy it slowly, there is a website called zecco.com with zero commission so you can afford to buy just 5 shares at a time, I think it is a good practice to buy 5 shares of everything you are interested in and start learning those 5 shares.
Yeh, tasr reached $35 before, IIRC.
good luck!
