That's not true at all, you are not impeded from carrying to and from, you are inconvenienced by having to park elsewhere, that's all.
There is no Constitutional right guaranteeing you to be free from being inconvenienced by your insistence on exercising your Constitutional rights.
This is an oversimplification, and I'd wager you know it, Luis.
Using my previous example of Qualcomm -- there was no other place to park. At all. Anywhere.
