Power hungry

I have seen a lot of great shows at the House of Blues. I have been to the one on Sunset Blvd. in Anaheim and of course San Diego, seeing acts like G. Love & Special Sauce, Slightly Stoopid, Cursive and most recently The Bloody Beetroots. The acoustics in all three locations have never let me down, providing explosive bass lines when necessary.
However, there is one thing that the House of Blues has failed to provide me with, and that is respect. Now, maybe I look like a troublemaker and the way I carry myself just asks to be forcefully shoved, but that's highly doubtful.
The first time I ever had a taste of the power hungry security guards was at a Slightly Stoopid show at the Sunset House of Blues. Surprisingly, someone happened to be smoking an unknown substance, most likely marijuana, during the show. Security, assuming it was my companion, bulldozed through the crowd, knocked him over and dragged him out. He was searched by the police and released back into the show after it was confirmed he was not in possession of anything illegal.
I understand the reason to suspect him for engaging in illegal actions. The crowd was a sea of people and it can be quite easy to make a mistake. However, the force that was used on him was unnecessary. Since that particular show, everytime I have been to any House of Blues I have noticed how incredibly tight their security is.
Without fail, I have had a security guard lay a hand on me in some way, shape or form. Once after having my ticket scanned at the entrance, I was pushed through the doorway in an urgent manner. There weren't any other people in line, so the argument that she was just keeping up the flow of traffic can be ruled out.
Most recently I was taking photos in the press area in front of the stage. I bent down to take a shot and as I snapped the photo I felt a powerful shove in my back. I figured I must have been in the security guard's way so I brushed it off as nothing. Then the same thing happened a minute later. I looked at the space behind me and the walkway, concluding that there was no reason for him to push me out of the way. There was plenty of room for him to get by without pushing me. A few minutes later, this happend for a third time.
I watched this security guard (throughout the show) rip people out of the crowd, dragging them by their heads, arms and torsos over the railing and knocking over innocent bystanders, only to drop the suspect a foot from the ground.
I was not injured and am not planning on filing a lawsuit against the House of Blues. I just don't need to be pushed around like I did something wrong. The bottom line is that the staff seems to be trained in the techniques of misuse of power.
