No need for justification ! Baby or no baby, pet or no pet, if you intrude uninvited on someone's property or in his home you need not be there and should be shot. If death follows so be it ! This will serve as a warning bell to all ill intended thieves and do no good and one will no doubt record a drastic fall of the number of robberies and thefts. No doubt about thar ! One must protect his castle at any cost and by any means necessary !
