luggage trouble ...

I had some luggage trouble on my flight back from Washington 3 weeks ago. I understand the security (TSA) and that they need to check everything, but why they are not able to close the luggage proper? Here have a look at my sportbag. They decided to tape it instead of closing the zipper, why? But the fun part, I start to collect the messages from the TSA that I allways find in my luggage, when they opened it.
