I am always - and I mean always - concerned when the federal or a state government uses force against citizens of the United States. However, there are times when force is justified. This may be one of those cases.
At around the 1:00 mark in the video, the officer keeps yelling "Move it, move it now!" to the gesturing and advancing man in the blue plaid shirt. The officer doesn't advance; in fact, he doesn't even keep his ground. He retreats slightly.
The man in the blue plaid shirt keeps advancing, aggressively gesturing and yelling, until he is upon the officers. At that point, he is tasered.
Reasonable minds can differ as to whether user of the taser was justified.
