Yes. If people are abusing the system, I don't see any reason why they shouldn't be held accountable. However, for most of the claims, if the individual files the claim electronically, it's supported by an electronic filing from their employer, so the EI system has the ability to very quickly verify the information that's in the application prior to paying out the funds.
Also, even if there is a short delay in terms of verifying the claim, the argument is that it should be paid from day one even if there is a short delay. It shouldn't be that you have to put in two weeks with no paid benefits. They collect money off your paycheque from the very first dollar you make, so why is there that two-week window?
You can't work during that two weeks or they'll take it right off your cheque when you do finally get it. They're penalizing people if they work during those two weeks. So why not start the claim from the day the person is unemployed?
