They are legal to use, but
only on the amateur bands. (Of course, you'll need to get a license first).
There was a lot of debate on whether they were legal, but the FCC finally stated that they were. Thus the older search results you found, such as
this one.
Since they are not type-accepted, they are not legal to use on other bands such as
FRS,
GMRS, etc.
If the radio messes up I guess the PD can shoot it.
