In English: IF A=TRUE OR B=TRUE THEN ACT

Yes? Is this what you want? If not, offer a better explanation. But let's
assume yes.

In Ruby (note the change):

if (@unit.custodian_id == session[:person_id] || session[:person_role] ==
'admin')
  # do something here
end

Avoid using a mixture of "&&, ||" and "and, or". They have different orders
of precedence. I prefer &&, ||, but that is a personal taste issue.
