It is well known that the relativistic equations have acausal
solutions, which have generally been ignored. This is particularly
true for higher spins. We consider spin 1/2 and spin 1 in this talk.
We analyze corresponding propagators which may indicate if a theory is
local or non-local. Negative-energy and tachyonic solutions are also
considered. The conclusions are paradoxical in both spins.
