Maybe it was not the best, but it was the only solution available.
A hint: It's nice to protect civilians, but even three capital ships will have a hard time taking down Rum Roger's Hyena. You had better to get a fighter on that. Pursuing pirates through debris fields is not a job for cruisers and battleships, even though the Liberty Cruiser is quite fit for the job because of its shape. Heck, hunt rather gunboats with that, anyway. A fighter can hide behind rocks.
