two law questions

i have two questions 150 words each.

1)What advantages and disadvantages are there with federal, state, tribal, and local trial courts all having jurisdiction over categories of offenses, such as drug offenses? Should there be one uniform jurisdiction designated to handle those offenses?

2)Imagine you are a prosecutor for the state of Arizona. The suspect you are investigating may be responsible for a spree involving activities in three different states. Before charging, would you consult with other prosecutors who may have federal or state jurisdiction over the case? Why or why not?
