What is a common reason for informants overseas to cooperate with investigators?

Informants overseas often cooperate with investigators primarily due to financial compensation or a distrust of local police authorities. In many parts of the world, individuals might feel that their local law enforcement is corrupt or ineffective, leading them to seek out external agencies that they believe can provide a safer and more effective means of addressing their concerns. The lure of financial compensation can also incentivize informants, as they may have economic needs that can be met through cooperation with foreign investigators. This combination of seeking a more trustworthy ally in law enforcement and immediate financial benefit is a prevalent reason for informants to provide useful information.
