Easily. That is one reason why ports and other national entry points have systems in place to detect that. Of course there is nothing to stop a bad actor from reaching the border or coast with a weapon and setting it off.
Yup, as a foreign national, I had to jump through a myriad of hoops to get a TWIC which enables me to enter and exit US ports freely without someone escorting me around. Fun fact: A TWIC allows even foreigners to register as a known traveler and TSA pre-screening, allowing me to skip a lot of the hassle when flying in the US.
Hell, getting a TWIC was the only reason why I bothered with getting an actual US work visa. I now hold B1, B2, C1/D, and it was all for the TWIC. If it wasn’t for that, I’d be fine just going on a tourist visa.
