The lead shot ban on water fowl here in B.C. was obviously a lie. The ducks they said died of lead poisoning used the the gvt. showing lead in the digestive tract, were of ducks X-rayed in various positions of whatever was necessary so shot appeared to be in the digestive tracts.
What also showed, was shot in some of the wings.
This, of course meant that the ducks were lost cripples, birds that escaped to die later & were collected and thus used for the purpose of their narrative of lead poisoning.
