Pros - They don't require anyone to take of shoes, belts, wires, etc. They are quick, easy-to-use, and they can search the entire body to see if there are any concealed items (like explosives strapped to legs, as in the December-25 Christmas attack). They can quickly be analyzed, and security lines would become much shorter.

Cons - Some people complain that they would invade privacy, as this is like walking naked. They worry that security agents could save these pictures and place these pictures on the internet or somewhere like porn.
