A business woman rented a second-floor office suite for her consulting business. It was located above a bank on the first floor, and partly on top of the bank vault. She obtained blueprints and brought drilling tools into the office. She studied bank activities and determined when at night she might be able to drill through to the vault. She inserted microscopic binoculars through the floor to explore the layout below. Before she started drilling, however, she noticed that more security persons appeared to be in the bank at night. Growing suspicious and losing the desire to take such a great risk, she hid the tools in her garage at home and did nothing further. A few weeks later, she was arrested by police based on reports regarding her suspicious nighttime activities. Does she have a viable defense to the attempted burglary charges?
