I feel so sick with guilt

An autistic man came into my work today for lunch and I think got overstimulated from the music, he kicked the kitchen door down and started throwing plates and yelling at everyone and they had to call the police and they really roughly tackled and restrained him. I feel so awful and upset because I know what its like to feel overstimulated and break down but he was also threatening us :( i wish they handled it in a slower manner rather than running in and knocking him to the ground. Ive been crying since I got home I feel terrible I needed to get it off my chest
