True we don't have enough information to make an intelligent decision whether the Officers actions were proper in this situation but there are a few interesting tidbits.
1. A couple called 911 because they were concerned for the boy’s safety. ("We called the police. My wife was afraid he was going to get ran over or hit," said witness Doug Messersmith. "He looked a little agitated but, other than that, he didn't look to be falling down drunk or anything like that.")
2. Police show up and find the boy has fallen off a bridge and is belligerent. ("However, Ozark police say the wounded boy was a threat." "He refused to comply with the officers and so the officers had to deploy their Tasers in order to subdue him," Capt. Thomas Rousset said. "He is making incoherent statements; he's also making statements such as, 'Shoot cops, kill cops,' things like that. So there was cause for concern to the officers.")
3. Officers did not cause any of the injuries to the boy. ("According to the doctors, all injuries are consistent with a fall," Samantha said.)
4. Could it be that Junior was attempting suicide? ("His father said Hutchinson did not jump but fell onto the pavement; however, no one knows why.")
5. Could it be that Junior was attempting to finish the deed my running into traffic? ("It's a big concern for the Officers to keep this guy out of traffic, to keep him from getting hurt," Rousset said.)
6. The only reports of the taser being used 19 times seems to be coming from the parents. ("Parents of a 16-year-old boy in intensive care with a broken back want to know why police Tasered their son 19 times rather than calling an ambulance for help.")
7. The parents also want to jump on the "Lets Sue the Police" bandwagon and need an excuse to do so. This statement contradicts the medical doctors working on junior. ("His father claims if police hadn't stunned the teenager 19 times, his critical surgery would not have been delayed by two days. “The Tasering increased his white blood cell count and caused him to have a temperature so they could not go into the operation," he said.")
8. If the parents win the lawsuit perhaps they will mandate all Officers carry a portable X-ray machine with them to determine if someone has any injuries before employing any use of force. ("I'm not an officer, but I don't see the reason for Tasering somebody lying there with a broken back. I don't consider that a threat," his aunt Samantha said.)
Again I wasn't there but perhaps Junior was having a bad day and jumped off the bridge.
Perhaps the Police arrived (and called an ambulance) then attempted to get Junior under control as he was trying to run out in traffic while ranting threats.
Perhaps the term "Broken Back" means cracked vertebrae not a severed spinal cord and junior was very capable of doing more harm.
Perhaps the parents are attempting to gain monetarily on their inability to raise junior properly and are making statements to the press to bolster their cause.
Perhaps the Police are doing a complete investigation before making any incorrect or unsubstantiated statements.
Now don't get me wrong, if the Police were out of line and abused their authority I and others in Law Enforcement will be the first to condemn their actions.
Perhaps we should wait until we get the rest of the story before we comment.
Looks like you will have alot more chances to test your theory.
