RE: spina

I guess plant spines would have been the original detterent fence
tribal herders in Africa still use thorn thickets pulled into corrals to
fence in thier stock overnight to protect them from predators including
humans.

and some of the orginal prisons would have been similiarly constructed in
these countries, although holding yard would have been a better term.

In South Africa they used to, and possibly still do, plant dense stands of
Cacti around the houses as protection.  One popular cacti, Cereus jamacaru,
was well equipped to ward off uninvited guests with spines up to 20 cm (10")
long.
Unfortunately this cacti has now gone feral in South Africa.
