No Pay for Police officers while under investigation, they should be suspended not placed on administrative leave

In 2015 990 people were shot and killed by the police, we are only half way through 2016 and another 509 people have been shot dead by the cops. Most of these officers while under investigation are placed on Administrative Leave, why? That is like allowing or telling them to go take a vacation while we work this out. They are still getting paid and receiving whatever benefits they are entitled which is being paid to them by use taxpayers. Why are they being allowed this luxury when someone is left dead by their hands and leaving families brokenhearted. These officers need to be held accountable, suspended instead of been given paid leave, when under investigation if should not feel like a privilege.
