Beaten before asking questions? by khaalis lee

In afghanistan theres a lot of political turmoil when it comes to us Americans intervening in current affairs.  i've recently read about multiple night raids undertaken by U.S special operation forces in Kabul. that doesn't surprise me considering its a supposed "tool" against insurgents. What concerns me is the harm we have done to civilians. "A man named Muhammad Younus, who uses a cane was so badly beaten by American soldiers that he could not walk for 20 days. He said that two of his brothers, both clerics, were killed." does that seem like normal protocol to you? Break into someones house and beat them senseless because they may be insurgents. Military officials say the campaign has disrupted whole insurgent networks in rural districts/ areas and along infiltration routes which apparently reduces large scale attacks in cities. Thats great but its been raising a question in my head... are there some if any American soldiers who feel that they have the freedom or authority to act like savages? Men have been shot and killed sleeping with their wives and children right next to them. " The method of the raids, especially the forced entry of houses and invasion of women’s quarters, let alone killing of women, is deeply offensive culturally to Afghans. Although coalition forces say most raids are conducted using a “soft knock” — calling by loudspeaker for people to come out —" based on the audio from the raid in the article the soldiers seemed pretty focused on separating the men from the women yet there have been numerous cases were that wasnt and option. just a soft knock then kill anyone you think is dangerous. I thought that we would be given a target and have to try to capture or kill the target if unavoidable all the while getting civilians out unharmed. Theres obviously a ton of civil rights being ignored in these raids. what i want to know is why? http://www.nytimes.com/2011/07/09/world/asia/09nightraids.html?pagewanted=2&ref=world
