What we have to remember, as others have stated, is that the veil is in the Department of Mysteries. No one but those who work there know exactly what is going on, and considering the name of the department, i doubt the unspeakables even truly know. when reading the book, I saw the veil as 'death', pure and simple, yet strangely complex. It makes sense that they would be studying it. it is afterall one of life's biggest mysterious.

So why was it created? its possible that the veil has been in existance longer than anyone knows. it could be as old as life and death themselves. OR, the DoM workers created it in order to study death.

As far as the security measures go...it was somewhere where everyone thought it was safe: the department of mysteries. Its not as though people are meant to wonder up to it idly. That department is one of the most, if not the most, secretive (and supposedly secure) departments at the ministry.

Of course there is no way to be sure about the veil as of right now, but your editorial got me thinking about the subject once again and i hope that soon we will have some more concrete answers (soon as in july 16th
