Taser's are considered non-lethal / less-lethal weapons...Borrowing from Wikipedia, "It is often understood that accidental, incidental, and correlative casualties are risked wherever force is applied, but non-lethal weapons try to minimize the risk as much as possible." In laymen's terms, while using a taser can sometimes result in a negative outcome, it is preferred over shooting someone, which guarantees a negative outcome. This is a primary reason many law-enforcement agencies resort to tasers.
Contrary to some of the statements here, you are not allowed to walk-away or refuse to be questioned by a sworn officer. It is true an officer should have probable cause to detain you. However, just because you disagree with his reasoning or feel otherwise, you cannot refuse to comply. Under the law, you are required to comply. If you feel the officer unfairly targeted you or behaved inappropriately there are legal and civil avenues you can pursue at a variety of levels.
Refusing to comply when stopped or questioned and attempting to flee; however peaceful, is an invitation in the use of increased force to detain you. Not to mention, suspicion was heightened when the person lied and gave a fake name.
I am not condoning the officer's or the citizen's actions as the story is vague at best. Making judgments w/so little info is an exercise in futility.
I avoid all UbiSoft titles, have for awhile. A shame because I like many of their games. The headache and BS associated with DRM just isnt worth it to me. I can find other games to enjoy w/o feeling like a criminal just because I reinstall it or upgrade hardware.
