In criminal defense and traffic defense much is made about the initial seizure or traffic stop. This is because if you fight the traffic stop and win, evidence is excluded which can lead to the entire case being dismissed. In regards to fighting a traffic stop, some people argue that there is a fundamental right to travel which is a defense to whatever violation of the traffic law that led to the seizure or the accusation itself. Essentially, the argument is that the fundamental constitutional right to travel invalidates whatever statute, law, rule or regulation the government is attempting to enforce or even the court's jurisdiction. In court, unrepresented defendants can be heard to argue things such as:
Arrests and the resulting criminal accusations happen every day. Common questions are how can they arrest when there are conflicting stories or can they arrest for whatever just happened. Unfortunately, that is the wrong question. If someone was just arrested, then the answer is yes the cops can and in fact they did just make that arrest. Now the accused has to defend themselves but the only place that happens is at a trial and that will not be for several months.
