If you have been around the activist community, and people who are willing to engage in civil disobedience... Remember, I was raised as a Quaker. When I was in Middle and High School we used to take a road trip down to the Nevada Test site for the annual protests there. My Friends Meeting used to hold actual civil disobedience training sessions. One of the members of my Friends Meeting (Salt Lake Monthly Meeting) engaged in a similar protest (a lone trespass, though it did not involve cuttng through fences) and was acquitted by a jury. I knew lots of people who decided to trespass during the protests, and many who chose not to. When I was in Middle School I helped build rock barricades on the road into the test site, so I think I have a sense of what people think who engage in protests of this sort.
When someone in these communities decides to undertake a protest of this magnitude, particularly when it is against a military installation, they tend to expect the absolute worst. This means inflated charges, possibly long prison terms, and so forth. When someone decides to do it anyway, the typical approach is to try to use all of this to one's advantage, to emphasize the political prisoner aspect, and to use the trial and jail time as a soap-box from which to make one's view known. Quakers particularly have a long tradition of this but so do some Catholic groups.
