Research Results Awaited with Interest

Jeffrey M Hansen wanted to know if the glass doors and windows of the Rock County Sheriff's Office were bullet-proof. In an experiment to find the answer to his research question, he repeatedly threw a large stone at the aforementioned doors and windows.
When officers went to investigate. Hansen gave himself up, holding out his wrists to officers, and admitted to causing the damage, telling officers to handcuff and arrest him. He told the officers he threw the rocks to see if the glass was bulletproof; investigating officers did find chips in the glass panes, a fact that will certainly inform the research project.
Ten people from a jail tour were in the lobby during the alleged incident.
Hansen was arrested for reckless endangering safety, criminal damage to property and disorderly conduct and is being held at the Rock County Jail until his initial court appearance.
We await the results of his research with interest, although one wonders if data produced for large stones (aka rocks?) is transferable to bullets.
