The mother was apparently the owner of the known firearms at the residence. Her PAL was reported to have allegedly been expired. The question now is why were the firearms not seized for unlawful possession? That's simple. Peoples PALs, drivers licenses, health cards, gym memberships expire all the time and they don't realize it until the need arises for that document. The RCMP's Continuous Eligibility Screening would not have flagged it as expired without a triggering law enforcement interaction being entered in a contributing police information system.
