what exactly shoud I write on to claim compensation for emotional trauma experienced in this violent accident?

You can't bring a claim like the one you described in Small Claims Court. There is a monetary damage limit in Small Claims Court of $5000. Filing a lawsuit against a City is not like suing an individual. There are special procedures and court rules that are required when suing a governmental entity such as a city. As the victim of negligence by a governmental entity you must be very careful in filing a claim against a city as special rules apply and if you fail to follow those rules, the courts will not hear your case and you will be left with nothing. For example, a verified claim form must be served on the authorized agent for the governmental entity. Serving a valid claim form on the government is a prerequisite to bringing a legal case against the government. The filing and presenting of claims against a governmental entity can be complex and confusing, so you are wise to consult with or retain an attorney. This response is general in nature and is not legal advice. No attorney client relationship is formed by it. Further, the response does not represent the opinions or views of LexisNexis or its affiliated companies.
