The law defines secure as follows:
46.13 3)
“Secure” means to take steps that a reasonable person would take to prevent the access to a readily dischargeable firearm by a child, including but not limited to placing a firearm in a locked container or temporarily rendering the firearm inoperable by a trigger lock or other means.
How do you see the described situation matching that description?
How is that a step a reasonable person would take?
And how would that be a reasonable interpretation of the law?
