There are Infrared video cameras available that can look through clothing. Airport security considered those but couldn't agree on who should operate them. Sony makes one model, and they are really revealing. Should be able to see bombs through burkas.
The roadside bombs are now camoflaged to look like concrete. The terrorists know where they are located because they also have infrared properties. They are combining low tech kamikazi warfare with hi-tech warfare re: roadside bombs.
