Sandra, you are so wonderful taking a stand like this. How can they arrest you when you are just telling the public the facts of what lies behind that pet-chain's windows? You are simply exercising the most precious of all the rights you possess as a citizen...freedom of speech. And you're doing it on behalf of those who have no speech to plead their own case...the animals.
I wish I were closer so I could help you in practical ways. Take care & let's know what happens.
