Sea Marshals?

What to do with the present day pirates?

Should freighters have Naval escorts?

Should there be well-armed sea marshals assigned to freighters?

I think a well-armed and well-trained team would be better than just having the crew be armed to protect themselves. Although a well-trained team with an armed crew as back-up may not be a bad thing.

Technology- is there a passive system that can be employed aboard freighters that would either disable the boat or the crew as they approach?

Amplified, directed soundwaves- we have deployed that technology in Iraq. I would bet that would stop their approach.

I am sure any readers will have their own suggestions.

What say you?
