Battle lines were drawn Thursday on plans to build a privately funded, multibillion-dollar hotel and casino on the grounds of the Nassau Coliseum, as supporters cited the prospects of high-paying jobs and new tax revenue and critics expressed concern the project could attract crime and spike gambling addiction.

Meanwhile, the lawmakers whose approval could make or break the project, including state, county and town officials, declined to show their hand, promising only a thorough review of the mega proposal.

Las Vegas Sands has proposed spending an estimated $4 billion to build a hotel with a full casino, performance venue, day spa, pool, convention space, restaurants, outdoor community space and tiered parking at the Coliseum site.
