Maybe he means a fashion crime. Tunnels under highways are so 1990's
Of concern is a proposed 150-foot bicycle and pedestrian tunnel slated to run under the Intercounty Connector from Briggs Chaney Road to Fairland Drive. "We said 'Whoa!' when we saw that," Bob McFadden, president of the Tanglewood homeowners recreation association said. "It seems like a crime waiting to happen."
What are the alternatives? You can go under the road, over the road (like at Georgia Avenue) or create an at-grade crossing. The best way to prevent crime, is to make sure the trail is busy. So they should be working for the best possible/most appealing trail that can be built.
