claim: Waiting periods for gun purchases may not make a difference, because "If somebody's decided that they're gonna take their life, they're gonna take their life."
evidence: Waiting Periods - Waiting periods are arbitrary impositions with no effect on crime or suicide, introduce no additional investigative avenues, and only burden law-abiding gun owners without changing how or when criminals obtain firearms. [...] - Most gun-owners own more than one firearm[5] and a waiting period could not possibly have an effect on those purchasing an additional firearm. First-time buyers seeking a firearm for self-defense would be affected by a waiting period that limits their ability to safeguard themselves and their loved ones. [...] Two-thirds of gun owners own more than one gun.[12] A cooling-off period for these gun owners could not possibly have an effect as they already own other firearms. Anecdotal evidence about a person who purchases a firearm and then immediately uses it to harm themselves or somebody else are just that: anecdotal. There is no scientific evidence that waiting periods have an effect on suicide, homicide, or mass shootings.
