Gravitational waves could be gravitationally lensed just like light. Strong lensing makes gravitational waves appear as repeated events with different amplitudes within our detectors. We will investigate recent forecasts for observed lensed event rates, including sub-threshold searches. We will also discuss a pressing issue related to the current lensed event searches: the rising probability of so-called search false alarms. We show how the inclusion of lensing statistics can help remedy this problem.
