Best practice

By now, the whole world has seen this.  A Google search brought up the South China Morning Post.  

A man described by his family as mentally ill and arrested for "trespassing" is led on a leash through the streets of Galveston by police on horseback.  Bland as grits, Police Chief Vernon Hale observes, "Although this is a trained technique and best practice in some scenarios, I believe our officers showed poor judgment in this instance and could have waited for a transport unit..."  Or nightfall.

I have no words.
