I have serious doubts that there are any “suitcase bombs” out there in the wilderness. It does seem to be the subject of constant apprehension, kind of like global warming. I guess we just never trusted the Soviets to tell the truth about anything.

"I have serious doubts that there are any “suitcase bombs” out there in the wilderness."

There have NEVER been any suitcase nukes. To assemble even a low yield weapon would require nearly 100lbs of shielding and fissionable material. A medium yield (50-100kt) weapon would be more on the order of two steamer trunks.

TV and movies show suitcase nukes in a Zero Halliburton case like this:

You might be able to squeeze enough fissionable material into this case but it would be unshielded and weigh 40 kilos.
