Flaws are created in the surface of one of the glass sheets in order to weaken the glass laminate upon an impact event on a first side of the laminate, while retaining the strength of the laminate upon impact on the opposing second side of the laminate. The opposing side of the glass sheet with the flaws or a surface of the other glass sheet may be strengthened with an acid etch treatment in order to further strengthen the laminate upon impact on the opposing second side of the laminate.
