Erikbal, . . . concealed carry or even owning a SD weapon is simply for that and that alone: Self Defense.
Your scenarios/situations don't offer any credible threats to YOUR safety or YOUR health. Therefore, . . . you better keep those bullets in the gun.
You are not authorized nor responsible to challenge every questionable event with a firearm and/or deadly force.
ONLY, when you have a threat to YOUR life, YOUR safety or someone else in a situation that you KNOW all the facts about, . . . are you authorized to use deadly force.
Other than that scenario alone, . . . leave it alone.
May God bless,
If you can breathe, . . . thank God!
If you can read, . . . thank a teacher!
If you are reading this in English, . . . thank a Veteran!
