Here is a informative video that Sahara Cares has put out for law enforcement to train them on how to recognize symptoms of autism and how to approach and handle these types of tough situations. There are also some great ideas for parents on what they can do to help protect their children.
You can find the video here. It is also available to purchase or download in the site. The video is going national but hasn't reached every state or department yet. Help to spread the awareness and advocate.
