Should l investigate the facts of my Florida car accident on my own?

No, you shouldn't look into the accident by yourself. What you should do is you should consult with an attorney who can get the proper people and right people out there to look into the facts such as expert witnesses and/or private investigators to go out there and talk to the witnesses and possibly any other people that may be involved. What's important to understand is that if you look into it by yourself, there's this emotional attachment that you're going to have to the case, which is completely understandable. However, that could cause you to blur the case as to what really needs to be done.
