My question involves civil rights in the State of: Washington

I’m Canadian, and I need advice on a tort case against US government. Few months ago I traveled to the US, and on my way back there was a US customs checkpoint. My car was searched and I was interrogated, where I had to answer some ridiculous questions. I attempted to assert my rights, but they said I have no rights since I’m not a citizen.

When I got home, I discovered considerable damage to my vehicle, which the agents had negligently searched. I called the nearest US customs office in Washington State, and demanded an explanation. The operator simply said that I could fill a tort claim form, and send a written complaint to a specified address. Which I did and received a written letter back from US customs stating they’re sorry for my inconvenience and they’d investigate my complaint.

Well it’s been 6 months, but I haven’t been compensated for the damages to my vehicle. So I guess the next step is to file a tort lawsuit against the US government. Btw this took place at an inland checkpoint, not the customs stations at the border.

Now I got a few questions:

1. Can I do this myself, or do I need to hire a lawyer? I’ve only defended myself in traffic court, so my courtroom experience is limited.

2. If I sue the US government, can I sue for a higher amount than the one listed on my tort form? I was originally only asking for damage to my vehicle, but I’d also like to sue for emotional distress, and violation of civil rights.

3. How exactly do I file this lawsuit, motion for discovery, etc.?

4. Will my case take place in state court or federal court?
