Generally, the First Amendment protects commercial speech. Commercial speech loses its protection if it concerns illegal activity or is misleading.. See, Central Hudson Gas & Elec. v. Public Service Comm'n of NY, 447 U.S. 557 (1980).
Though the ad upset you, there is no indication that the commercial is unprotected under the First Amendment. However, you can call the television station, the law firm, or Bar Grievance and voice your concerns.
You should consult an attorney immediately. He/she will assist you in explaining what evidence, if any, may be suppressed on constitutional or procedural grounds. Your extensive prior record makes it crucial that you take this seriously- the likelihood of jail time increases substantially with every conviction.
If you cannot afford a private attorney, apply for the services of the public defender.
Your rights to pursue for damages, and the landlord's liability may be defined or limited by your lease agreement. You should consult with a lawyer, have him/her review your lease, and discuss whether pursuing a claim against the landlord, directly, is viable.
It may be medical malpractice. Cases like this are determined by expert medical testimony as to (1) what is the standard of care for such medical situations; and (2) how did the actions taken by your doctors deviate, if at all, from that standard of care. Consult with an attorney regarding potential recovery for you and/or your child.
The First Amendment protects self-expression (even if it is poor taste) from governmental intrusion. That would prohibit the State from charging you criminally. However, private citizens (e.g. your employer) are not subject to the same restrictions. If you are being a jerk, the people around you may start treating you like one.
Perhaps, in the spirit of civility, you can turn the other cheek-- even if it requires you to forgive someone. Remember that the hard thing and the right thing...
Yes! You must request a trial in writing, or your right to a trial will be waived. Contact a private attorney immediately (you are not eligible for representation through the public defender, because your citation does not carry potential jail time). Fighting this could save you money in fines, and insurance premiums (your car insurance premiums will increase with a conviction).
Generally, a "probation before judgment" (PBJ) disposition can be expunged. However, the Maryland legislature, in order to discourage drunk driving, specifically exempted DUI charges. A PBJ disposition for a DUI charge may not, by statute, be expunged. See Md. Ann. Code, Transportation Article Section 21-902.
Criminally: you would have to prove you acted in self-defense (and the force you used must be commensurate with the force of the aggressor)
Civilly: yes, you have a duty not to punch people. You breached that duty. And you caused him damage. You could counter-sue for your own damages, but it doesn't seem like you sustained any.
If you are served with criminal or civil summons, consult with an attorney immediately.
