Are killer robots a necessity?

There are additional obstacles to finding programmers and manufacturers of fully autonomous weapons liable under civil law, in which a victim files a lawsuit against an alleged wrongdoer. The United States, for example, establishes immunity for most weapons manufacturers. It also has high standards for proving a product was defective in a way that would make a manufacturer legally responsible. In any case, victims from other countries would likely lack the access and money to sue a foreign entity. The gap in accountability would weaken deterrence of unlawful acts and leave victims unsatisfied that someone was punished for their suffering.
