You can’t find a remote wireless device so cheap, reliable and working within any distance you want.
Oh, I missed the word “suicide”.
Well, as far as I know using remote triggering as backup is not unusual for muslim bomber groups. Suicide bomber could get scared in the “right” moment so somebody else presses remote button.
