Ahmaud Arbery's father: His death was a modern-day lynching

We remember Benjamin Crump from the Trayvon Martin killing.  

George Zimmerman -vs- Trayvon Martin

 Now I have a question in mind: I noticed that the guy taking the video follows the jogger for quite a little while.  What in the world was so interesting that he did that?  Joggers aren't so unusual that they capture much interest at all, yet he follows him into this thing that amounts to a trap.  There was no call for anyone to accost Ahmaud at all.  There is absolutely no legal justification for any armed person to get so close to Ahmaud such that any struggle for a weapon should ensue.  If they believed Ahmaud was a suspected criminal, the only legal option they had was to alert the police.  They had no right to approach, less distract or detain anyone.  They could follow and that is all the law allows them to do.  So, that this became a killing means it was an intentional cold blooded murder.
