This was a targeted attack on the faculty at Scripps Ranch High School.

These were not accidents, these were not pranks.

They are very powerful, very unpredictable and very volatile.

That's something I learned in art school. I studied graphic design in Germany, and my professor emphasized the responsibility that designers and illustrators have towards the people they create things for.

They are deceptively simple. I admit that. But for me, all my life I try to simplify things. As a child in school, things were very hard for me to understand often, and I developed a knack, I think. I developed a process to simplify things so I would understand them.

When the time came for me to go to college, there was only one scholarship that my high school offered at the time and I didn't win that one, but that didn't stop me. I went on to college anyway. I worked my way through it and paid my student loans for 11 years.
