This is why gun permits should be "shall-issue" rather than "may-issue." In other words, there should be a clear set of objective requirements; if an applicant meets these objective requirements, the government official should be required to issue the permit. This would be similar to driver's licenses.
"May-issue" jurisdictions, such as California, give too much discretion to local officials, leading to arbitrary decisions and cases of bribery. Most states are "shall-issue" jurisdictions and do not have this type of problem.
