Suggest you heed the advise and counsel of your attorney, and perhaps schedule another meeting with your lawyer as you don't seem to be fully...

Should I leave this alone?

Agree with what's been posted and wish you well, however proving that Walmart knew or should have known of the leak is likely not to occur.

What can be done about it ?

Request the police officer to file an amended report. No requirement that it be done. Be sure to report the incident to your insurance carrier.

Son was hit in face with ski pole unprovoked. split lip and scar

Potential claim agaisnt the parents/guardian. Claim against facility, much more problematic. Hope your son gets better soom. Good luck.

What to do?

Speak with an attorney asap. Probably one who handles criminal matters. Good luck.

Though no damage whatsoever was done to either vehicle does she have anything legal wise to worry about.

Your post certainly suggests that the other driver didn't even know about the tap. Are you sure there is not more to the story?

What do I do now that the other party has lied about the way an accident unfolded?

Sorry, but at best there is a question of fact that you are not at fault. You are not to pass unless safe to do so. Good luck.

Where can I find another attorney to take over a case when one quits?

Very tough to establish legal malpractice. Conservative Florida Governors have seen to that. Try searching for another lawyer. Good luck.

My question is how do I approach the adjuster? I want to present my settlement demand because I think liability is clear.

Sorry, but it is doubtful that an attorney would drop a case for this reason alone. If you have a viable case, then you will have little problem...

Can I file a counter claim against them under this same case? Should I?

Adopt the answer of Attorney Sommer. If you are being sued, you are entitled to counsel at your company's expense. Highly doubtful any lawyer...
