The check-in system is not the problem. A dishonest person is always gonna be dishonest, no matter how difficult it is to lie. What was gonna stop a person before from driving right past the check in station and heading on home, not tagging a deer? Nothing, it's just easier to place blame on the new tag system. This is not the problem, over harvesting of deer is the problem.
Honestly, I'd be inclined to believe that more people cheat the system now that the deer tags can be printed off the computer rather than the old colored deer tags you were issued at the store. Multiple copies can be made of the same tag, so if a dishonest hunter wanted to "temporarily" tag a deer with a spare copy, they could fill the tag out, making them "legal" until they got home, disposing of the tag and not tagging the deer online. To me, that is the bigger issue here with a dishonest hunters. If a ODNR officer was to stop this hunter on their way home, outside of the officer tagging the deer in for the hunter as a "courtesy," there is no way for that officer to know he's just gonna go home and dispose of the "spare" tag, not check the deer in.
IMO, there is no easy answer to solve Ohio's deer herd population. In most areas, bag limits need to be cut, but there needs to be more done than just reducing tag numbers. If coyotes are a problem, then that issue needs to be looked into. If the insurance agencies and FB have too much control over the DNR, then that needs to be addressed as well. Also, maybe it's time to look into crop damage permits and how they are issued. Get hunters involved with the "nuisance" problem, or you don't get the tags. I'm just not smart enough to know what a good path forward would be.
