Tarrant County My neighbor pointed his shotgun at me and said he was going to kill me. What steps do I take to ensure he is prosecuted to the fullest?

While I was in the public street and my neighbor was standing on his front porch%2c he pointed his shotgun at me and said he was going to %22blow my _expletive_ head off%22. I am the Director of Compliance with my local Homeowners Association%2c I was performing the duties of my position by taking a photograph of the mans car that was illegally parked when I heard his shotgun rack up. So I was amazingly fortunate to take a photgraph at the very moment he lifted his gun and cocked it. This is the second time the man has threatened to kill me%2c although the first time%2c almost a year ago%2c there was no gun involved. I reported the first instance%2c and there is a police record documenting both instances. The situation has escalated to the point a shotgun is now involved. I am very concerned for my safety and that of my family. I would like something done about this man and his death threats. I have spoken to a detective%2c but this man is still free and should be in jail%2c in my opinion
